This was a perfectly serviceable space thriller that explores what happens when geopolitics follow us into space. The result, as you might expect, are complicated and not always as they may seem. It takes critical thinking and an open mind to examine all the implications, particularly when cut off from the typical channels one might use to address the effects.

What an excellent space mystery/thriller! The plot really keeps you guessing and does a great job switching between the POVs. You leave a POV wanting to come back to it but also wanting to read the next POV. Not a lot of authors do that well, balance the intrigue of the different characters.

I appreciated all the relevant scientific detail. It was fascinating and didn’t feel boring or bogged down. I was initially a little disappointed to find this was regular thriller versus what I consider a true to genre science fiction (missing the aliens or futuristic tech) however the plot sucked me.

I felt like I had lived on the ISS for a week after I finished this book. Space is ever intriguing to me. This book is perfect for those NASA, astronaut, space groupies.

Thank you to HarperVia and NetGalley for this ARC. Inner Space is set to publish on 7/15/2025.

I'll start by saying this book was translated from Polish to English, but the translator did a fantastic job and the reading was very fluid.

I really enjoyed this space psychological and political thriller. I appreciate Jakub Szamalek's research and providing a realistic view of life on the International Space Station and the toll this profession has on personal and family relationships.

The book switches between various points of view and timelines. It adds important perspective between the astronauts, political heads, and family. The plot was fast-paced and engaging throughout the book. While I don't think there was a "significant twist" as you might get from the thriller genre, I do believe it falls in line with the realistic view the story takes.

I loved the afterward where the author asks the question of whether this story really could have taken place. A great "what if" question with the final statement of "Not yet, at least." This story certainly spoke to today's politics along with sexism and racism.

While the premise appealed to me, nothing really happens for most of the story. I enjoyed the details about the ISS but the plot was WAY too slow.

Thankfully this story is based on a scenario of what could have happened at the ISS (International Space Station) should the US and Russia become involved in an adversarial situation. The ISS is divided into two sections, one US and one Russian. When the US side develops a problem with mounting amounts of ammonia, the two countries blame each other for the problem.

With four people in the American ISS and two in the Russian, there is an an unsolvable problem. Adding to the problem is that the Americans return vehicle can only hold three. Does the US leave one astronaut to stay on the ISS with the only way to return in an emergency is by the Russian capsule.

Adding to the problem is that one of the Americans is anti-Russian and not afraid to show it. When the Russians decide to test a missle that can destroy satellites during and American EVA, things get overheated.

I gave this three stars because is presents the characters as one dimensional and the 'final' confrontation seems to fabricated.

Let me start with how beautiful the translation of this book is - there's none of the stilted, awkward turns of phrase that often mar translations from Eastern European area languages (at least in my small, humble reading experience). Absolutely perfect.

Inner Space is one of those books that in this (North American) political climate hits very close to home, up to a point. Russian and American astronauts are aboard the ISS and a mysterious ammonia leak is threatening the health and future of this expedition. Russia is (obviously) blaming the American cooling system, whereas the USA is (obviously) suspecting Russian interference.

Aside from the myriad details about the structure and function of the ISS and the difficulties of keeping it in running order, Inner Space delves into the interpersonal conflicts between the astronauts as tension ramps up and ammonia levels continue to rise.

Large spoilers - At one point, the "close to home" feeling falls apart. I'm not sure when the Polish edition of this book was published, but there's an explicitly racist, sexist, aggressively MAGA character who takes a violently anti-Russian stance that completely drives the climax of the book. And now MAGA (in the real world) is Russia's best friend. But had current events not happened as they have in this year of Our Lord, 2025, this book would be spot on. I do not count that against the book at all - it's a work of fiction and does not need to adhere to real life, but the sheer amount of detail the author has put into researching everything made it feel real.

Great book, 4.5/5. Tense, beautiful, and with so much humanity in these flawed characters. Thanks to author/publisher/NetGalley (and translator!) for the opportunity to read.

Inner Space is a fun hard science thriller with excellent pacing and interesting twists. It is descriptive the technical parts, especially the International Space Station, are easily accessible and understandable by people who are not technical. Each of the characters is portrayed as a real person with real motivations and weaknesses.. All the characters get torn between what they should do, what they can do, and what would be best for themselves. All of the book weaves together and engaging, thoughtful, and suspenseful story that holds your attention and makes you want to know what is going to happen next!

This was a great book! It had the great elements of a psychological thriller, plus the science fiction elements made this a great book and a great story! It was well written, it kept me hooked from the start and it was full of lots of twist and turns!

Thank you to NetGalley, to the author, and to the publisher for this complimentary ARC in exchange for my honest review!!!

This was a great space thriller that was translated fairly smoothly. The writing style felt more formal but that was just probably due to the translations. The politics sort of mimic today's and it is overall a very compelling novel to read.

Thank you to NetGalley and to HarperVia for the ARC of Inner Space by Jakub Szamalek.

It's hard to fully describe the plot of this novel without giving away any spoilers, but basically, an American and Russian crew are aboard the International Space Station. An ammonia leak begins after a solar flare when all the astronauts are confined to their quarters for safety. Is it some sort of accident from the flare causing the leak? Or is it sabotage? And when the truth is figured out, will there still be a space station?

In a story that takes us on the ground, into space, with family members and with political aficionados, we see the wide range of how the events on the space station play out for the astronauts, their families, and their countries.

While the book starts slow, the real action not beginning until after the 50% mark, this gave me hints of Michael Crichton in the way the events are recounted and described. When the action is high, it feels most similar to the intensity of his novels, especially with each action's far reaching implications in the moment and for earth. It also has the Crichton style of describing characters and their actions while still keeping you a bit distanced from them - so while I did not feel a strong emotional connection to any of the characters, I felt I understood their machinations and personalities. I think in the first 35% we don't truly have an idea yet of what the incident is going to be or catalyze toward, but once it does, the story has incredibly engaging action.

in the down times, Szamalek really goes into depth on how the space station functions and what the astronauts are experiencing. I found his acknowledgement that the same experiments being run by the astronauts can be run by drones or robots - meaning the reason we spend so much money to maintain humans in space is to study humans / for the prestige of the old space race. I think that adds a lot of interesting context to everyone involved in aerospace/space/defense budgets/political supporters.

I think, reading this in February 2025, that the topics covered in the story also are really interesting in today's political climate / today's international relations, and it's sure to be food for thought for plenty of book clubs that take this story on.

4.3 stars

Translated from the Polish by Kara Beresford.

It’s 2021 and Lucy Poplasky is the commander of a six month stay at the International Space Station at a time when cooperation between the U.S. and Russia is at a very low ebb. There are two cosmonauts and three other Americans on board during this time, one a space tourist tourist who is horribly space sick. Back home Steve Ayer’s at NASA keeps constant tabs on what is going on while Lucy’s husband worries for her safety.

An ammonia leak threatens the astronauts, could it have been caused by sabotage? More fractures among the group appear. What will become of this mission?

This was a really good book and I am enjoying it even more in retrospect since I’m now reading Samantha Harvey’s ORBITAL which is also set on the ISS (I nearly always enjoy books set in space that aren’t hard sci-fi and aren’t fantasy/crazy alien stories.) This was a nice space thriller that also speaks to the politics of the day as well as sexism, racism and what money can buy. Highly recommended if the premise sounds good to you.

The story is a good one and the trivia about the manned flight into space are fascinating, but I could not tell if the more formal (stilted?) style of writing is just the author's voice or is because of the translation from Polish to English. At some points it's just fine, but at others it seems a bit uneven. For those who are not distracted by the style, the story is intriguing.

Thanks to HarperVia and NetGalley for this ARC of 'Inner Space' by Jakub Szamalek.

This is a really tight and enjoyable thriller set on the International Space Station where an ammonia leak sparks an international crisis both in orbit and on Earth.
\We know something seriously untoward transpires on this mission since each chapter is preceded by the relevant page of transcript from a congressional hearing but it's so well paced and constructed that it just drives the narrative and gives hints as to what's to come but not in a spoiler sense.

A bit like in 'The Martian' you're unobtrusively informed and educated in the science and practicalities of being in space for prolonged periods of time. The effects of that existence on the human body and mind and, conversely, the effects of the human body and mind on that environment are laid out in a compelling way. Really fascinating and done in a such a way that it's very enjoyable and not at all dull (but can be a bit gross!).

There's plenty of action as well as talk and much geopolitics in this one so very appealing in multiple ways. In some ways it put me in mind of some the classic thrillers of Robert Ludlum and Frederick Forsyth.

The characters are believable throughout and you're kept guessing about who's done what until the author is ready to reveal it.

Recommended.

Loved it!
It is both a psychological thriller and a hard science fiction novel, and I think both aspects are perfectly executed.
The details and description of the life aboard the ISS paint a very vivid picture of the situation of the characters and make for a completely immersive story.
The thriller and political aspects are great, and the characters are well fleshed out but still mysterious.
The story moves fast and the stakes are so high I couldn't put it down.
This is a very compelling book and I would gladly recommend it.

When I first realized that this was being translated from Polish to English, I was hesitant to read. When reading translated books, sometimes the language does not sound smooth and fluid. I’m happy to say that is not the case here. The writing was great.
I LOVE when a book takes place in space. It’s very easy to drop the ball with them because the space setting can sometimes become repetitive and boring. However, Inner Space was Intense and action-packed, and I had a good time reading it. There were some definite Andy Weir Project Hail Mary vibes going on at times.
I liked the length of the chapters and I also liked that almost every chapter began with a Hearing Transcript as it really added some character to the story.
My only con is that some parts were a bit too verbose and made me feel like I was reading a textbook so I started to lose interest.
Can’t wait to read more !
