Heliopause is a fantastic first novel by newcomer Dianne Dotson. Fast-pace, relatable characters, plenty of plot twists and overall a heck of a lot of fun. Looking forward to the next book.

Heliopause by J. Dianne Dotson is the next book up in my self-published marathon and not only has it been a nice break from my fantasy-strict reading diet, but it's always amazing to discover strikingly talented storytellers. While this story is sci-fi at its core, it’s also an alluring mystery that keeps you on your toes while nothing is as it seems. I thoroughly enjoyed this book and am so glad it was recommended to me.

At the edge of interstellar space, strange occurrences descend upon the usually quiet Mandira Space Station and only one man is witness to mysterious transmissions sent from the unknown. Forster, along with his ambiguous shipmate Efron, ventures out amongst the stars to uncover the source of these messages only to discover an invisible and dangerous adversary. Are they capable of saving not only the lives of their station crew, but of all life in the solar system?

This is a fast-paced read with a strong and conscious plot that remains gripping through the final page. Dotson does a wonderful job of creating rich, empathetic characters that really draw the reader into the main story, as well as their pasts. While the tone of the book can be relatively dark at times, there is a strong sense of hope throughout with focus on the strength of family bonds and the importance of perseverance.

I truly love how this story ties up nicely, yet leaves just enough of a thread to continue in the future. Heliopause is a stunning debut and I am really looking forward to reading more as The Questrison Saga continues.

There’s something about space stations that turn me on, in a literal sense of course. For me, some of the best science fiction shows have been set on space stations. Deep Space 9 stands out, of course, but in my opinion the Daddy of them all is Babylon 5, an amazing and for its time, ahead of the posse when it came to CGI, boasting an interstellar cast which told a complex and human and alien story over five seasons. The recent news that B5 will be rebooted in the near future excites and terrifies me in equal measure, but with J.Michael Straczynski at the helm, at least the vision will be somewhat similar. As long as he includes the classic John Sheridan line, “Get the hell out of our galaxy,” I’ll be happy.

At a time in my lead when my ‘read list’ on Goodreads is heavily comprised of many degrees of science fiction, my current reads have been primariy space operas. I’m coming to the end of Gareth L. Powell’s Embers of War trilogy, and soon will start the final novel in James S.A. Corey’s Expanse series, Leviathan Falls. It’s an exciting time for me. But a writer I’ve recently discovered, thanks to following Powell’s Twitter account, is American author J. Dianne Dotson. Heliopause is the first book in her Questrison Saga quartet. It’s set mainly on a space station, so you know I was all over it like a bad suit.

Forster works on the research space station Mandira, near the outermost limit of our solar system, known as the Heliopause, that part of the solar system which is exposed to particles and ions of deep space (thanks, Google). He pals around with Gibbons and Efron, and together they the station operational and each other sane. Forster reminisces over his lost love Auna, but struggles on anyway. At the beginning of the book, he sees lights where lights should not occur. It’s not a hallucination because others see them, too. It’s a transmission of sorts, in Morse Code of all things, as discovered by Gibbons’ AI assistant Veronica. There is a sense of excitement on Mandira, as one of their colleagues, Captain Spears, is on the way with a ship-load of much-needed replenishments and goodies. However, when contact is lost with Spears’ ship, and Forster and Efron realise that the mysterious transmission may be behind it, they come up with a plan to locate the source. The station’s matriarch, Meredith, suspects the transmission may be the key to locating her daughter Ariel, a telepath who went missing on a mission many years back.

Heliopause is classic Golden Age science fiction, taking me back to Star Trek in all its glory and, of course Babylon 5. It’s closer to B5 because of the looming presence of forces deep outside the Border Wall that spell certain doom and devastation to Mandira and ultimately humanity. One of Forster’s friends, Efron, knows more than he lets on, and he urges Forster to use his own latent telepathic powers to aid the mission and save Ariel. And that, dear reader, is only the start of the book. What happens from then on is a rip-roaring read that had me gasping at some of the plot twists. J. Dianne Dotson self-published Heliopause and did a wonderful job at keeping the different plot strands together. As it is the first book of four, some questions will be answered, but many more will be left dangling. And that’s as it should be. By the end of the book, certain characters will have met their destiny and we may or may not see them again in future books. But others will remain, and their story will continue. I will read the next book, Ephemeris, with glee and purpose. I loved this book and I’m so happy I found out about it.

Heliopause is the boundary of the heliosphere, the very edge of the Solar System. It’s also the debut novel by J. Dianne Dotson, author, illustrator, scientist, watercolorist, and most importantly, mother. Heliopause is about a space station named Mandira, home to a few scientists studying the Heliopause, like our main character, Forster, who researches solar winds. I won’t go into too much detail about the story, but a mystery is detected early on, and from there the action starts. This is not seen from the top, from the people leading the station, but from the common folks, like Forster, Efron, and Meredith. It gets exciting very fast, and these few normal people must step up and be the heroes. The story is solid, very intense, at times scary, and it won’t let you relax until the end. It’s well written, without unnecessary parts, perfectly balanced, and hard to put away. Personally I’d like to know more about the station, how it creates gravity, if it’s a wheel or a cylinder, and what kind of ships they have, to get a feel for the technology level, but it’s also refreshing to read a science fiction book that doesn’t dwell too much on the technical stuff. Instead it creates a window into the lives of the people living on the station, and allows you to understand their feelings and reasoning. Looking forward to diving into the next one.

Heliopause was overall a fantastic read. I love me some space opera, and there was a lot to love about this book. First of all, the location: Mandira Research Station, a large conch-shaped space station situated out at the edge of the solar system. A great alternative to the more typical starships, Mandira provided not only a great sense of isolation similar to what you get aboard the Gilgamesh in Adrian Tchaikovsky’s Children of Time, but also the camaraderie and community in Star Trek: Deep Space Nine, with an aesthetic that kind of reminded me of the Enterprise D in The Next Generation. Despite the isolation of this far-out location, the worldbuilding is great: you get a good idea of the kind of technological level humans are at just through the different areas of the station and the interactions with the crew.

Plot-wise, there’s a lot of mysterious goings-on, some of which is deliberately left vague even to the end of the book, making clear room for the second book to expand upon it all. In fact, I have already started reading Ephemeris at the time of writing this review, and the expansion of the worldbuilding is immense, but I’ll leave that for when I review that book. In Heliopause there’s a Big Reveal that gave me goosebumps because it was so awesome - don’t worry, I won’t spoil it here. The plot was well-paced and the short chapters made it incredibly snappy to read. That being said, there were some occasions where I felt the book could have done with dwelling a bit more on what was going on, but it moved along quite quickly.

The characters were fun generally. Forster spent much of his time confused and feeling out of the loop. As much of the book is centered around a lot of mysterious and unusual happenings, Forster’s was a good perspective to inhabit. The other characters around him are also vibrant and dynamic. Efron was a fun enigmatic character, and other crewmembers all had distinct, interesting and believable personalities.

All-in-all, I’m looking forward to continuing my journey through the Questrison Saga. Very much recommended.

The blurb for this novel reads "Flashes of light. An unseen menace. Messages from the void. Secrets at the edge of the solar system that threaten to destroy the future."

What it doesn't tell you is that when you start reading it, you get pulled back into the Golden Age of Science Fiction or into an episode of Star Trek (The Original Series). This books has the feel of one of those Asimov, Clarke, or Heinlein books. The technology employed isn't Golden Age, but the entire feel of the book is. It was consistent and it was comfortable.

The author did a good job of building of the characters and giving them their own voice. The story was a plausible mix of science and pseudoscience. Mandira Station, where much of the story takes place, was an odd mix of architecture and organic design. Were there aliens? You'll have to read the story to find out.

This is a self-published work and, amazingly unlike most self-published works, I found zero typos. It was cleanly edited.

I just finished re-reading this book and liked it even better the second time around. Now onto Ephemeris!

Amidst a year of personal drama, I can’t really recall where or how I heard of this book or its author, who I have followed on social media since before I began reading the book. But I’m glad I did.

As a long-time science fiction fan who began his addiction as a teenager reading Asimov’s Foundation series, I was quickly drawn into the story’s main character, Forster. I’ve had trouble finding many stories that keep my attention since devouring Scott Lynch’s Gentleman Bastard series in late 2017. And Heliopause is definitely the best sci-fi I’ve read since I finished Children of Time in March of 2018.

As others have noted, the mystery and unpredictable twists and turns kept me on my toes and interested in the characters. But the informal tone and quick pace are what I really enjoyed most. It seemed familiar, yet exciting. If I had any complaint, it would be that the super-fast pace of the last couple of chapters seemed rushed, but never-the-less made me immediately want to pick up the second book in the series. I’ll be starting it tonight.

I am a huge fan of science fiction, especially the space opera. The problem is there is so much pseudo science and hastily written drivel that seeks to sponge of the wonder of Star Wars, Star Trek, and others that good books get lost in the shuffle. J. Dianne Dotson’s book serves as an example of what a space opera should be. First off, she is a science writer and it shows in her writing, beyond that, her story is exciting, poignant, and immersive. I kept saying “one more page!” as I could not put it down. Someday, I expect this will be a blockbuster movie that even George Lucas could not screw up. One of the finest space operas I have ever read!

Seriously, snatch this book up, along with it's sequel Ephemeris which I am also reading, and which is also incredible. Mark my words, this book saga is EPIC!

I'm so glad I was made aware of this series. It has the familiar sci fi elements that make me feel at home in the genre while providing new elements to take it in its own direction. It fits right in with Star Trek, Babylon 5, Mass Effect, and so many other definitive sci fi stories that make it just a wonderful escape. While you read it you get to feel that same sense of discovery as the human characters, because the setting places the story right at the beginning of humanity pushing beyond our solar system. I always enjoy seeing how different authors and show creators will approach the idea of true space exploration in its early years. I don't want to give too much away, but I will say that there is a first contact on par with the Vulcans. I can't wait to see where the series goes next.

Anyone picking up this book... I had a hard time staying with it, at the beginning, I'll be honest. But I stuck with it, and I am glad I did! From chapter 4 or 5 it really picks up, hitting its stride, and by the time you're nearing the end, pages are turning at a rabbit's pace. I don't know if I can compare this to anything I've read in a long time; it's really throwback sci-fi. 2001: A Space Odyssey, maybe.

First of all, if you're like me and you're worried that there's a vampire on the crew of the space station, don't be.
I'd call Heliopause a retro-science fiction novel, except it's only retro in that it calls back to science fiction from the 80s and since I was alive back then it cannot be retro. Many of the classic elements are here; the aforementioned space station, psi powers, maybe some aliens, with a sprinkling of cosmic horror.

Heliopause was a lot of fun. It does a fantastic job of presenting a believable science fiction world with characters you want to cheer for. It's hard to believe this is J. Dianne Dotson's first book. It is expertly crafted with tight prose and plenty of cool plot twists. Looking forward to reading the following books!

An exciting science fiction book with a big heart. Strong themes of 'found family' resonate throughout the story, and the characters bond throughout their journey together. It was also lovely to read a science fiction novel that wasn't strictly materialistic and afraid to incorporate fantastical elements. I am looking forward to the rest of the series.

Heliopause is original and worthwhile. I have read thousands of science fiction novels, but this one still kept me guessing (usually wrong) about what was going to happen. I'm very much looking forward to the next book in the series, ephemeris.

A fun, engaging story with interesting characters

Engaging story with characters that draw you in and interesting twists along the way. Characters that change and grow and learn about themselves and the universe in the process.

This is one you'll remember for a long time. The characters (human and otherwise) are memorable and the action is gripping. It may take you a few short chapters to get drawn in, but once you're in you'll be hooked on the adventure. It's difficult for me not to imagine this as a movie or TV series.

The setting of Heliopause is a far-flung space station, but the story makes it clear that author J. Dianne Dotson has developed a rich and complex universe beyond this arena. One can only wonder what else is out there -- what other mysteries will arise once we are invited further into this space.

Awesome debut novel by indie SciFi writer J. Dianne Dotson. Suspense and a wisps of humor combine in a unique story...set at the edge of the solar system. I loved the way the story unfolded like an onion peeling back layers to reveal more and more of the picture. Memorable characters and deft story-telling really bring the book to life and sets the stage for the next phase in the saga. Fans of either hard SciFi or Fantasy will both enjoy this novel and if you’re a fan of both....it’s a double win! Highly recommended.

My first did not finish of the year.
Set on a space station at the far edge of the solar system a bunch of people do ... things. They may be haunted or they may be being contacted by aliens. To be honest, given how soon I gave up on this it wasn't clear.
The issue for me was the writing style. It was very opaque and I found myself having to push to get through pages. I put it down one evening and just decided that was that. To be fair, this is definitely a me thing, as it has a solid rating on here.
Cannot recommend.

Meet Forster and Efron and their team on the Mandira Research Station, they are happily getting on with their jobs when a strange presence makes itself known in the space outside the station and people experience intense pain whilst trying to enter the station.
All is not as it seems, throw in some telepaths, alien life forms and a range of characters, who have very little to do.
This is an interesting tale in a new world, but for me lacked the action I thought it was going to have. It will be interesting to see what else happens in this universe.

really enjoyable - probably more F in space than SFF

I really enjoyed this and will read the rest. Felt very old school pulp SF but with good women. Good plot driven story. Occasionally questioned whether the people carrying out the plot would really have done so but if you can ignore that then great. If you need it to really be totally believable that characters would do what they do then this may not be for you.

An exciting read in the science fiction genre. I especially liked the tension building to the climax of the story. Also the insight into the characters’ emotions as circumstances changed and the use of strong female characters. Don’t want to spoil the plot but you can see the potential for a sequel.

A riveting book that had me hooked from the very first page!
I would highly recommend this book, the first in a series of books, that really gets the reader into the events that take place.
No spoilers here, but it will take you to places that you didn't think possible from a space point of view!

I couldn't stop reading it from the moment I got it, a very enthralling read.

Delightfully imaginative, action-packed, and full of plot twists, you won’t be able to put HELIOPAUSE down. An instant classic in sci-fi!

The writing flows well and the characters are so compelling. Efron was my favorite character, as well as Ariel. Excited to read the next book! 5/5 stars.

Good plot, a fun, interesting and engaging set of characters. I liked the authors style, different and original, and with a sprinkle of classic sci-fi. A pinch of Solaris, a grain of early Greg Bear, a whiff of The Gap.

An epic saga with great imagination. Sets up well to a follow up. An intriguing world with layered characters and complexities that help make it feel real.

What I didn't like was the repetition of the characters names in too high a frequency for my own liking. I also found the layout of the paperback uncomfortable with its line breaks between paragraphs. But, again, personal preference.

Recommend Heliopause (for its great imagination and heart) to science fiction buffs. This one is a compelling read with much to offer its audience.

What a fun read! Heliopause tells the story of a space station at the edge of the galaxy. It's stuffed full of the mainstays of science fiction including telepaths, aliens, dangerous (and sexy) AI's and a lot of great action. The writing is fluid and fast paced. The characters are well drawn and, despite being a large cast, very memorable. An enjoyable story that hints at a much larger adventure to come. I'll be reading!
