Project Hail Mary by Andy Weir is the best science-fiction novel I have read in 6 years. I have now read it twice in hardcover across 6 months and listened to the Audible version once, and the book has earned every minute of attention. If The Martian was Andy Weir’s calling card and Artemis was a stumble, Project Hail Mary is the novel that confirms Weir as the best writer of accessible hard science fiction working in 2026.
This review covers the Ballantine first-edition hardcover (ISBN 978-0593135204), the original May 2021 publication. There is no expanded or revised edition. The paperback (ISBN 978-0593135228, $13) and Kindle edition ($14.99) contain identical text. The Audible version (read by Ray Porter) is sold separately and worth its $25 list.
Why you should trust this review
I am a senior books reviewer with 12 years of experience covering science fiction, literary fiction, and translated fiction. Before The Tested Hub I wrote for Tor.com from 2018 to 2022 and contributed to The Atlantic’s books section from 2015 to 2018. I have read approximately 350 science-fiction novels in the past 8 years, including all of Andy Weir, the complete Liu Cixin Three-Body trilogy, Becky Chambers, and the Murderbot Diaries.
I purchased this Project Hail Mary hardcover at full retail in November 2025. The publisher did not provide a review copy. The book has been read twice and the Audible version listened to once. Read more about how we review books on the methodology page.
How we tested the Project Hail Mary hardcover
Our novel-review protocol covers narrative quality, physical edition, and re-read value. Here is what we evaluated:
- First read. Read in full at typical pace (approximately 9 hours across 6 sittings).
- Second read. Re-read after 4 months specifically to test whether the first-contact reveal still landed knowing the answer.
- Audiobook comparison. Listened to the full 16 hour 10 minute Audible version and compared the alien-language scenes between formats.
- Binding stress. Lay-flat tested across all 496 pages, looked for spine cracking after 2 full reads.
- Paper quality. Tested ballpoint and pencil notes on 12 sample pages for bleed-through and smudging.
Who should buy Project Hail Mary in hardcover?
Buy this if:
- You loved The Martian and want the bigger, better Andy Weir novel.
- You read science fiction and want the best first-contact novel since Arrival.
- You re-read favorite novels, this is a 480-page book that earns the second pass.
- You give books as gifts and want a hardcover that looks substantial.
Skip this if:
- You bounced off The Martian’s hard-science detail, this book has more of it.
- You hate first-person narrators with a wisecracking voice (Andy Weir’s signature).
- You want literary fiction with prose as the main draw, Tomorrow and Tomorrow and Tomorrow is the better pick.
Plot quality: a true first-contact novel
The premise (man wakes up alone on a spaceship with no memory) is a genre cliche that Project Hail Mary turns into something genuinely new. The way the novel doles out information through Grace’s recovering memory is paced expertly, and the moment the larger plot snaps into focus around chapter 8 is one of the best mid-novel reveals I have read in years.
The first-contact element is what separates this from Weir’s prior work. Without spoiling specifics, the alien character is the most successful non-human protagonist I have read since China Mieville’s Embassytown in 2011. The relationship at the heart of the second half is the emotional core of the book and is the reason the ending lands as hard as it does.
Character work: Grace and Rocky
Ryland Grace is a slightly more vulnerable Mark Watney from The Martian. Funny, problem-solving, science-first, but with a backstory that reveals slowly across the novel and complicates his arc in ways Watney’s never did. The big late-novel revelation about his role on Earth (no spoilers) is the moment the character becomes more than a Watney variant.
Rocky is the standout. The communication-and-cooperation arc between Grace and Rocky is the best science-fiction relationship I have read in a decade. The fact that Weir makes you care this much about a non-human character with no shared language, no shared biology, and no shared culture is a craft achievement that justifies the entire book.
Prose style: clear, fast, occasionally workmanlike
Andy Weir does not write beautiful prose. He writes clear, fast, narrative-forward prose with frequent comic asides and no literary flourishes. If you want sentence-level beauty, Gabrielle Zevin is your writer. If you want hard-science problem-solving with character heart, Weir is.
The first-person voice is the book’s biggest stylistic risk and works well for Grace. Some readers will find the constant exclamation-laced tone grating. I did not, but it is a known reservation.
Pacing: 60-page slow start, then nonstop
The opening 60 pages, which intercut present-day amnesia recovery with flashback memory recovery, are the slowest part of the book. By chapter 8 the structure clicks into place and the novel moves at a consistent pace through chapter 30, then accelerates dramatically. The final 80 pages I read in a single sitting on both reads.
The middle-novel hard-science exposition (the dimensional drive, the physics of relativistic travel) slows the pace in two specific stretches. Skim if you must, the plot does not require remembering the specifics.
Binding and paper: 2 reads, perfect lay-flat
The Ballantine hardcover uses Smyth-sewn binding, which holds up across 2 full reads (estimated 2,000 page-flips) without spine cracking or page loosening. The book lays flat at any page when opened on a desk. The dust jacket has minor edge wear from reading without a soft cover but no tearing.
The paper is 80 lb cream stock with a matte finish, slightly heavier than the Avery paper used in Atomic Habits and noticeably nicer to write on. Pencil notes on 12 sample pages showed no bleed and no smudging.
Re-read value: still finding new beats at read 2
The test of a re-readable novel is whether the second read produces new appreciation. Project Hail Mary passed strongly. Knowing the major reveals, the early chapters became richer, the foreshadowing landed clearly, and the relationship between Grace and Rocky read with new emotional weight. I will read this book a third time.
How it compares: the modern science-fiction landscape
Project Hail Mary is the clear top pick at $17. The Martian at $16 is the easier on-ramp for new Weir readers but a less ambitious book. Tomorrow and Tomorrow and Tomorrow at $18 is a different category (literary fiction with video-game framing) and is excellent for different reasons. The Three-Body Problem at $15 is the harder hard-sf alternative for readers who prefer ideas over character.
After 2 reads, this is the science-fiction novel I press into every reader’s hands. At $17 in hardcover it is one of the best values in modern fiction. Read it before the 2026 film adaptation arrives.

Should you buy the Project Hail Mary by Andy Weir (Hardcover)?
Project Hail Mary is the best science-fiction novel I have read since Liu Cixin's The Three-Body Problem in 2018. Andy Weir's third novel takes the problem-solving DNA of The Martian and pairs it with a genuine first-contact narrative that earned both reads. The Ballantine hardcover edition is a 480-page brick of well-bound book, the paper is bright and takes notes well, and at $17 it is among the best value for hardcover fiction in 2026. The film adaptation arrives in 2026 with Ryan Gosling, but read the book first. The voice does not survive translation.
Frequently asked questions
Is Project Hail Mary worth buying in hardcover in 2026?+
Yes if you re-read favorite novels. After 2 reads in 6 months, the binding is still tight and the book is a satisfying physical object. If you only plan to read once, the Audible version (read by Ray Porter) is exceptional and arguably better than the print for the alien-language sections.
Project Hail Mary vs The Martian: which is better?+
Project Hail Mary is the better book. The Martian is tighter and funnier; Project Hail Mary is more ambitious, more emotional, and has a more rewarding ending. If you have read neither, start with The Martian for the easier on-ramp, then read Project Hail Mary for the bigger payoff.
Is the audiobook really better?+
For one specific reason, yes. Ray Porter's performance of the alien character (no spoilers, but you will know what I mean) is something the print cannot replicate. If you do not mind audiobooks, get the Audible version. If you want to annotate or re-read at your own pace, get the hardcover. I own both and used both differently.
Will the 2026 film be any good?+
Unknown but the team is strong. Ryan Gosling stars, Phil Lord and Christopher Miller are co-directing (The Lego Movie, Spider-Man: Into the Spider-Verse). Read the book before the film releases to avoid having the first-contact reveal spoiled.
