Why I love it

Mike Chen
Author, We Could Be Heroes

Before I was a science-fiction writer, I was an engineer, which means I learned to see the world in numbers. In fact, I tell my daughter that everything is numbers, from music to technology to sports. Numbers are the cause of and solution to every problem. That makes math a superpower, and one of the things I adore about Andy Weir is that his heroes use math and science to get out of any jam.

Project Hail Mary continues that tradition. When Ryland Grace wakes up alone aboard a strange spacecraft, he must discover why he's hurtling through the cosmos far from Earth—and why he can't remember his life. As he puts the pieces together, the secrets of the titular project are revealed, twisting and turning the story in ways that really shouldn't be spoiled at all. The surprises keep coming chapter by chapter, making for a fast, fun read that puts you right alongside Ryland as he solves—with math, of course—the universe's greatest mysteries in an epic attempt to save planet Earth.

For a book driven by science, Project Hail Mary is fueled by so much heart; it’s also about hope, the human condition, and unlikely friendships. Those things all come together for a story that is so many things, from riveting discovery to laugh-and-cry characters to fist-pumping ingenuity. Oh, and it's one heck of a page-turner. And it'll make you want to thank your high school science teachers. If that's not the best testament for this book, I don't know what is.

Ryland Grace is the sole survivor on a desperate, last-chance mission--and if he fails, humanity and the 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, he realizes that an impossible task now confronts him. Alone on this tiny ship that's been cobbled together by every government and space agency on the planet and hurled into the depths of space, it's up to him to conquer an extinction-level threat to our species.

And thanks to an unexpected ally, he just might have a chance.

Part scientific mystery, part dazzling interstellar journey, 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 absolutely love Andy Weir’s humor, and “Project Hail Mary” didn’t disappoint. The humor gives the book much needed levity, as it did in “The Martian.” Ryland and Rockys’ relationship was fantastic.

  • Marlton, NJ

    If I’m honest, it sometimes got a little too “sciency” and I didn’t understand it all, but the story was fabulous! Loved the characters, loved how the flashbacks unfolded, and loved Rocky and Ryland!

  • Santa Monica , CA

    I don’t know if this was better than The Martian, but it was better than Artemis. Completely unexpected plot, doesn’t go the direction you think it will, but highly enjoyable. 100% recommend! FISTBUMP

  • Hinesburg, VT

    Love love love this book!!! Even if you don’t like sci-fi, this is THE book to read! Especially since we’re in a pandemic & have watched everything get turned upside down; this story just resonates.

  • Mattawan, MI

    Fun! And tough to put down! The science got a little science-y, probably more explanation and detail than I really needed. But what a fun premise! Ending was a lil cheesy but I liked it ????????‍♀️

  • Parker, CO

    The only reason I read this book is because I loved the Martian. I don’t really like reading books about science. However this book blew my mind in a good way. I absolutely loved it from start to end.

  • Scranton, PA

    LOVE! Some of the best science fiction I’ve ever read. The friendship between Ryland & Rocky is one of the greatest literary duos of all time. Hysterical, fun, & heartfelt. A perfect ending too ❤️

  • Marietta, GA

    Science fiction is not typically my genre, but this is thought provoking and just simply amazing. Everyone should read this. It’s BOTY quality - wish it had been published in time to qualify!! LOVE!

  • Gorham, ME

    This is probably the best book I have read in 2021. I don’t know how Weir does it, but he manages to make really hard sci-fi accessible, funny, and relatable. Rocky is now an all time fave character!

  • Boerne, TX

    Even if you think you don’t like science fiction and you hated science in high school, read this book. This is an extraordinary work of fiction with tremendous brain, humor and heart. Truly excellent.

  • Steep Falls, ME

    I’ve never read a science fiction book so fast before! The main character’s passion for science gets you incredibly interested. You’ll be hanging on to the edge of your seat on this space mission!

  • Memphis, TN

    At first I was worried it would be too similar to The Martian, but that was quickly turned on it’s head as the plot unfolds. It is very science-heavy (some of which went over my head) but I enjoyed it

  • Smithsburg , MD

    I was worried I wouldn’t understand any of the science but Weir writes it so it’s easy to understand. I really enjoyed this book!! I loved Ryland and Rocky’s friendship and the ending was perfect!

  • Arlington, VA

    It’s hard to put into words how much I loved this book. Such a great story, full of humor and science. It was hard to put down. I absolutely recommend this book and already can’t wait to reread it!

  • Salt Lake City, UT

    ★★★★★ The detail into the science makes the fringe science so real! I would also recommend the audio book, R&R’s conversations were done perfectly. Oh and the ending was absolutely lovely.

  • Apple Valley, MN

    LOVED this book. So many layers to it that kept pulling me in. It has it all; mystery, thrills, science, nerdy plus big thought provoking topics that keep you thinking long after you are finished!

  • Holt, MI

    This page-turner was gripping and easy to read despite being heavy on scientific language. I loved Grace’s self-realizations and how endearing Rocky became. A great premise and a satisfying ending.

  • Waukesha, WI

    Andy Weir has to be one of my favorite authors. The scope of his imagination and his ability to craft an engaging narrative with interesting and diverse characters is second to none. 100% recommend!!!

  • Crisfield , MD

    This was every bit as good as The Martian. I love the wit and emotion of the main character. There is lots of science to process, but I loved the relationship between Rocky and Garland. A best book

  • Denver, CO

    I rarely shed a tear when I read a book but I got choked up reading the last page. I loved the journey of Ryland and Rocky and the fate of both characters was so beautiful and unexpected! What a book!
