Here's the pitch that gets the skeptics in your group to say yes: a man wakes up alone on a spaceship with no memory, and the first thing he has to figure out is his own name.
Project Hail Mary is the rare science fiction pick that readers who "don't do sci-fi" finish in three days and then won't stop talking about. It's funny, tense, and surprisingly tender. It also happens to be packed with things to argue about — which is exactly what you want from a book club book.
The questions below are sorted by spoiler level, so you can start safe and go deep once everyone has finished.
This book has one of the best reveals in modern fiction, and half your group probably went in cold. Decide up front whether the whole meeting is spoiler-friendly. If not, open with the spoiler-free questions and make the group agree to a clear signal before moving on to the endgame.
Our guide to a book club spoiler policy covers how to handle the member who is still on chapter 20. For this book, it's worth doing.
These work even if someone is only halfway through.
- Ryland Grace wakes up with amnesia and has to rediscover who he is alongside the reader. How did the slow return of his memories shape the way you felt about him?
- Weir builds the plot out of problems that get solved with real-feeling science. Did the science make the book more exciting or occasionally more work? Where did you skim, and where did you lean in?
- Isolation is the engine of the first act. How does a story with one character and no one to talk to keep you turning pages?
- Grace is a former science teacher, not a career astronaut. Why do you think Weir chose a protagonist like that? What does it change about the tone?
- The humor in this book is constant, even when the stakes are enormous. Does that make the danger feel smaller, or does it make you care more?
If you want a ready-made list in one place, get the Project Hail Mary book club kit — it tags every question by spoiler level so you can pull exactly what your group is ready for.
This is the heart of the book, and the section that tends to get the warmest response from a room.
- Two beings with nothing in common — no shared language, no shared biology, no shared sense of the world — still build trust. What does the book suggest are the minimum requirements for friendship?
- Much of the story is about how the two characters learn to communicate, not just what they say. Which moment of breakthrough stuck with you most?
- Weir keeps the friendship free of romance, rivalry, or betrayal. Did you expect something to go wrong? Why do you think he chose to write a pure friendship?
- How does the relationship change Grace? Compare the man at the start of the book to the man in the final chapters.
- Teamwork across a huge difference is a common theme in science fiction. How does this book's version compare to others you've read?
This is also a good place to ask the group about their own unlikely friendships. The answers get personal quickly.
The book asks a hard question and doesn't let anyone off easily: how much are you allowed to take from individuals to save everyone else?
- The people running the mission make choices that are difficult to defend. Where do you draw the line between necessary and unforgivable? Did your answer shift while reading?
- Eva Stratt is one of the most polarizing characters in recent sci-fi. Is she a villain, a realist, or something harder to name?
- Grace argues for individual choice even when the numbers say otherwise. Is that principle or privilege?
- If you had been given the same information as the decision-makers, what would you have done differently — or the same?
- The book frames saving humanity as an obvious good. Does it earn the right to do that, or does it skip over a harder conversation?
Expect this section to run long. Plan for it.
Only open this section when you know everyone has reached the last page.
- Think back to Grace's memory loss and what he learns about why he's on the ship. How did that revelation change your read on the earlier chapters?
- The ending is not the one many readers expect. Did it feel earned? Would you have written it differently?
- Grace makes a final choice about where his life goes from here. Is it a tragedy, a triumph, or both?
- What do you think the book is ultimately saying about courage — that it's a decision made once, or something you keep choosing?
- If this story were told from another character's point of view, whose would you want to read?
Skip the generic ones. These set the tone without spoiling anything:
- If you woke up with no memory, what's the first thing you'd check for to figure out who you are?
- What's one thing from your own life you'd want a stranger to know about you immediately?
- What's the best science class you ever took, or the worst?

You don't need to go full spacecraft. A few simple touches carry the theme:
- Snacks: Anything that's meant to be eaten one-handed from a shelf — crackers, cheese cubes, trail mix, and a plate of cookies. Grace spends a lot of the book surviving on tubed rations, so you have permission to make the table feel indulgent in contrast.
- Drinks: A strong pot of coffee, plus something sparkling for the group.
- Decor: String lights and a dark tablecloth. If someone owns a star projector, bring it.
The kit includes more themed pairings and decor ideas, and our book club food ideas post has more themed snack inspiration if you want to go further.

A few things that help with this particular book:
- Start with the feeling, not the facts. Ask "what was your favorite moment?" before anything about plot mechanics. Some members will have loved the science, and some will have tolerated it.
- Let the science nerds talk, but time-box it. Five minutes of "how does that actually work" is a gift to the group. Fifteen minutes is a lecture.
- Save the ethics questions for the middle. They need energy, and they work better after people are warmed up.
