A LONE ASTRONAUT.
AN IMPOSSIBLE MISSION.
AN ALLY HE NEVER IMAGINED.

RYLAND GRACE is the sole survivor on a desperate, last-chance mission—and if he fails, humanity and Earth itself will perish.

Except that right now, he doesn’t know that. He can’t even remember his own name, let alone the nature of his assignment or how to complete it.

All he knows is that he’s been asleep for a very, very long time. And he’s just been awakened to find himself millions of miles from home, with nothing but two corpses for company.

His crewmates dead, his memories fuzzily returning, Ryland realizes that an impossible task now confronts him. Hurtling through space on this tiny ship, it’s up to him to puzzle out an impossible scientific mystery—and conquer an extinction-level threat to our species.

And with the clock ticking down and the nearest human being light-years away, he’s got to do it all alone.

Or does he?

An irresistible interstellar adventure as only Andy Weir could imagine it, Project Hail Mary is a tale of discovery, speculation, and survival to rival The Martian—while taking us to places it never dreamed of going.

I’m super late to the party with this one. I’ve heard nothing but rave reviews and kept meaning to pick it up, but I was never really in the mood for it. I’m not much of a sci-fi reader, so it was hard for me to even think about picking this one up. It was never at the front of my mind. Finally, I decided to give the audiobook a listen. The movie was about to come out and I wanted to get the book out of the way so I could watch it. Did I like it? Yeah, I did. But sadly, I didn’t love it the way a lot of people did.

The story follows Ryland Grace, who wakes up on a spaceship with no memory of who he is or why he’s there. His crewmates are dead, he’s millions of miles from home, and as his memory slowly comes back, he realizes he’s on a last-chance mission to save humanity from extinction. There’s something eating the sun. Earth is dying. And somehow, Ryland has to figure out how to stop it.

Alone.

Except he’s not entirely alone. Without spoiling too much, Ryland encounters another being facing the same problem. Their suns are dying too. And together, they have to figure out what’s causing it and how to stop it before both their worlds are destroyed.

On the plus side, I really loved the relationship between Ryland and Rocky. Watching them learn how to communicate was fascinating. They don’t speak the same language. They don’t even perceive the world in the same way. But they figure it out. And watching them work together to solve this impossible problem was genuinely interesting. Their friendship is the heart of the book, and it’s what kept me engaged.

The writing is very strong. Andy Weir knows how to build a world and create high stakes. The audiobook narration by Ray Porter is really strong. He does a great job bringing Ryland’s voice to life and differentiating between characters. If you’re going to experience this book, I’d recommend the audio version.

That said, I often found myself drifting off while listening. The text is very science heavy. Weir goes deep into the mechanics of everything and how and why they work. And while I appreciated the realism and the attention to detail, it kind of bored me. Not because it was bad, but because it slowed things down for me. There are long stretches where Ryland is working through a problem, explaining the science behind it, testing theories, running calculations, and troubleshooting. For some readers, that’s exactly what they want. For me, it felt like the story kept hitting pause so we could sit through a lecture. I get why it’s there. It’s necessary and makes the world feel real. It also makes Ryland’s solutions feel earned, but it made me zone out more than once.

I think I’ve come to realize that I enjoy watching sci-fi more than I enjoy reading it. When I’m watching a movie or a show, the science can happen in the background. I can see the results without sitting through the explanation. But in a book, especially one this detailed, I have to wade through every step of the process, and evidently, that’s just not my thing.

That said, I completely understand why so many people loved this. The science is impressive. The problem-solving is clever. And the friendship at the center of the story is genuinely touching. If you’re someone who loves hard sci-fi with detailed worldbuilding, this is going to be a home run for you. But if you’re like me and you’re more interested in character and momentum than technical explanations, you might find yourself struggling to stay engaged. It’s not a bad book. It’s actually a very good book. It’s just not the book for me.

Overall, I’m glad I read it. I get the hype now. And I’m curious to see how the movie handles the science-heavy sections. But this one didn’t grab me the way I hoped it would, even if I can appreciate what it does well.
