A book worth rereading
Format: Hardcover
This was a book club pick. Honestly, I wouldn't have chosen to read this myself, but I'm glad that I did. I would have missed out on an incredible story.
I've been reading a lot of thriller and fantasy books lately, that I forgot how much I enjoy sci-fi. This brought it back for me. There's a lot of science-heavy discussions in the book and I loved it! When I got to a subject or term I didn't know, I would go online and learn more about it. I feel that Grace is a dork like me because he wouldn't curse. He had little anecdotes he uses in place of swearing. Something I definitely do myself!
A lot of the book is the MMC talking to himself. Surprisingly, it worked. There's so much humor that it kept the story going. There was not a lull. Usually I dislike info-dumping as an introduction to get all the background story told, but I didn't mind it at all. Maybe I'm being biased because I love science talk.
**SPOILERS AHEAD**
What makes the whole plot engaging is the fact that the plot doesn't seem too fantastical. It's something that could happen. There's a lot of ethics and morals involved in determining what should be done. I would hate to be in a position where I have to chose what's best for everyone. That's why Stratt is a necessary character. I hated some of her decisions and how she operated, but you need someone who's focused on the general welfare of humanity. I would be too focused on myself, my family, etc. As much as it hurts to admit, I'm selfish (and a coward) like Grace. I wouldn't want to die. But was it right for Stratt to force him on the mission? This could also be taken religiously. If God has a plan and things happen for a reason, is it our right to deter what's going to happen? God wiped out the world many times because of humanity's sins, what if this was God's doing? So many questions and debates on right vs wrong, ethics vs morals, and religion vs humanity made for a incredible book club discussion.
I love how this book ended. I wish I could continue reading about Rocky and Grace's adventures, it's that fascinating. However, I think Grace staying on Erid was the best outcome. If the roles were reversed, I don't think Rocky would have the same welcome. I feel that those in charge would have dissected and kept Rocky hostage, all in the name of science. Just as the Astrophage were first introduced, the first things the scientists did was poke and probe. Essentially torturing the Astrophage to see what makes them tick. I think Rocky would have the same fate.
Oh, and my favorite part is the relationship between Rocky and Grace. I cried so many times when I was reading. Scared that something bad was going to happen to either of them. Especially in the scene where Rocky busted out of his tunnel to save Grace. I got upset and told the book that 'if Rocky dies, I swear, this is the worst book ever!' And the scene where Rocky learns about radiation poisoning. How he slowly becomes aware of what happened to his crew, his friends. I was a mess.
This book is definitely one that I could go back and reread.
I did watch the movie afterwards. There's a lot of differences to adapt the story to screen, but it was okay. They got the humor down pat, but I didn't get the direness of the whole situation nor the special bond that both MCs had.

Excellent story
Format: Kindle
This book is worth your time. It is a great introduction to a variety of scientific disciplines without insulting the reader. It also respects and understands humanity, engineering, history and political science. Then it lays that foundation to tell the story of a unique friendship of two beings with mutual goals who have to communicate and problem solve together. Along the way, you can really contrast how Grace and Rocky do it, vice the Hail Mary team did it.

A Brilliant, Emotional, and Unforgettable Sci-Fi Adventure
Format: Paperback
Project Hail Mary by Andy Weir is one of those rare novels that delivers everything you could want from science fiction: gripping suspense, fascinating science, humor, heart, and a genuinely moving story about survival and friendship.
The novel follows Ryland Grace, a middle school science teacher who wakes up alone on a spacecraft with no memory of who he is or why he’s there. As his memories slowly return, the stakes become clear: humanity is facing extinction, and he may be the only person who can stop it. The mystery unfolds at a perfect pace, blending high tension with moments of discovery that keep you turning the pages.
What makes this book stand out is how seamlessly it combines hard science with accessibility. Like the author’s earlier work, the scientific details feel authentic and well researched, but they never overwhelm the story. Instead, the problem-solving becomes the engine of the plot. Each obstacle feels real, and the solutions are both clever and satisfying.
The biggest surprise—and the emotional core of the novel—is the relationship that develops during the mission. Without giving anything away, it adds warmth, humor, and depth that elevate the story far beyond a typical survival thriller. By the end, the novel becomes less about science and more about courage, trust, and the willingness to sacrifice for others.
The pacing is excellent throughout, with a balance of suspense, humor, and heartfelt moments. If there’s a small drawback, it’s that some plot developments feel a bit convenient. But the strong characters and emotional payoff more than make up for it.
Overall, this is a must-read for fans of science fiction, space exploration, and anyone who enjoys smart, character-driven storytelling. It’s thrilling, funny, deeply human, and surprisingly emotional. I finished it feeling both entertained and uplifted. Highly recommended.

Spoiler-free Review - The Martian Dialed Up To 11
Format: Kindle
If you loved the Martian in either book or movie form, Project Hail Mary will likely delight you.
The main character (who I'll leave nameless to avoid spoilers) is nearly identical to The Martian's lead, Mark Watney. They have similar personalities, the same fundamental mission of surviving in a hostile environment, and both use real-world biology, chemistry, and physics to solve their problems from start to finish. The book provides an early test for whether or not you'll enjoy it: on page five, when our protagonist is being quizzed by an annoyingly paternalistic computer that is demanding to know the cube root of eight, our hero replies with the smart aleck answer: "two times e to the two-i-pi". If you find this interaction amusing, all good; if it's off-putting, turn back now.
In fairness, Project Hail Mary shares The Martian's flaws as well. The protagonist's character is a bit better developed - but only slightly. The conflict is entirely man-vs-environment. And though the protagonist is often in situations that might cause one to ponder the essential truths of the human condition, he never does. His personality and behavior as a sarcastic problem-solving scientist / engineer are pitch-perfect but the book rarely goes any deeper. He has an established motivation and a flaw to be overcome - but these are really just superficial grace-notes (see what I did there?). This is not Crime and Punishment. Instead, it's a page-turning action-hero book - where instead of firing shots, the action hero saves the day by doing science really well. Books that celebrate real science are rare, so if that's what you came for, you're going to love what Project Hail Mary delivers.
Although largely similar, there are four main ways in which Project Hail Mary differs on the Martian so I'll touch on those now:
1. The stakes are higher - much higher! In The Martian, Mark Watney is already a bit of a super hero - he's an astronaut after all - and all he really needs to do is stay alive. In Project Hail Mary, our hero is much more of an every-man and his job is nothing less than to save the human race.
2. The Martian is told in chronological order. In Project Hail Mary, our hero awakens with a serious case of amnesia and can't even remember his own name. He starts his adventures at essentially the most dull part of his recent life. As time passes he both tackles dramatic new challenges and remembers the wild adventures that brought him here. Andy Weir does a fantastic job of interweaving the past and the present and the result is a very effective narrative framework that lands on a "Wow!" moment at the end of nearly every chapter.
3. Project Hail Mary is a buddy story. In The Martian, Mark Watney is alone in his battle against the elements of Mars for nearly the entire book. By contrast, Project Hail Mary, once it really gets going, is absolutely a tale of buddy-bonding. This surprised and, ultimately, delighted me. It helps give the protagonist a bit more of a human side. And the team problem-solving scenes are, again, pitch-perfect.
4. Project Hail Mary puts the 'fiction' back in Science Fiction. In The Martian, leaving aside the opening wind storm and the closing chapter of wish-fulfillment heroics, we are essentially in a very tightly written NASA simulation. I found this incredibly enjoyable - but one could reasonably ask, where are the big ideas? Where are the bold 'what ifs'? The answer is, they're in Project Hail Mary! The science is still real and omni-present, but the fiction is big, bold, and awesome. If you're main draw for the Martian was the NASA lore and you wished Weir would write an even tighter sequel detailing the Apollo 13 events, you may be a bit disappointed - but everyone else is going to love this change of pace!
So that's it in a nutshell: Project Hail Mary is a fantastic next book to read after The Martian. It's a clear spiritual successor but brings new ideas and structure to the game. Enjoy!

Excellent Hard Sci-Fi… Until the Politics Pull You Out
Format: Kindle
I was really excited to dive into Project Hail Mary. As a longtime Isaac Asimov fan, I’ve been craving fresh, modern hard science fiction that actually respects the science. This book delivered — at least for a while.
The author injects real science into the story in a way that’s both fun and fantastic. You don’t need to be an engineer to follow it; a solid high-school education is plenty. The concepts stretch your imagination without ever feeling impossible, and for the first chunk of the book I was hooked. I genuinely thought I’d found a new favorite author.
Then the jarring interruptions started.
Out of nowhere you get yanked out of the immersive sci-fi world by modern political pandering that feels completely unnecessary. A random parenthetical about Columbus “discovering an already inhabited world” when comparing something to the New World. Casual pronoun lectures. Characters selected or described by race and identity in ways that scream “check the boxes.” These moments don’t serve the story — they feel injected. Once you notice the author’s leanings, it becomes hard to unsee.
Each time it happens, the fantasy evaporates. It takes several chapters to sink back into the story… only for the next micro-lecture to pull you right back out.
Overall, I loved the writing, the hard science, and the imagination. It’s some of the best sci-fi I’ve read in years. I just wish the author had trusted the story instead of sneaking in real-world politics. It’s like eating the best meal of your life… and then finding a hair or two in it.
Strongly recommended for the sci-fi, with the above caveat.
