Full disclosure: The Martian is my favorite book, maybe ever, so I’m coming into this review with a fair bit of bias. That said, in my opinion Project Hail Mary is a worthy follow-up to The Martian, with the same kind of humor, heart, high stakes, and rock-solid science.
Here’s the gist (without spoilers): Dr. Ryland Grace wakes up alone and confused in a spaceship (the eponymous Hail Mary) VERY far from Earth. He’s lost his memory, and his two crewmates died in suspended animation. It’s up to him to figure out exactly who he is, how he got there, what the ship’s mission is, and how he can complete it on his own. And he’d better hurry, because all of life on Earth is at stake.
If that sounds intense, it is – but Grace also makes jokes and laughs as much as he can, while not shying away from the huge responsibility, sacrifice, and loss he’s facing. I really thought this book was effective for several reasons: first, the science. As in The Martian, this book’s science reads to me like plausible and real explanations and solutions. It felt like a book that Weir had a lot of fun writing, with a ton of research to back him up. Second, the character of Ryland Grace was very well done; his emotions, backstory, and feelings of being overwhelmed, repeatedly, make him a relatable narrator that you root for to succeed, while his humor and determination keep the action moving forward at an addictive pace. Third, the narrative structure worked really well. If you’ve ever seen the DC TV show Arrow, you might recognize the strategic use of flashbacks to reveal key information at just the right time. Weir moves carefully and explicitly between Grace’s struggle in the present and all the events in the past that culminated in his being on the ship. It all works together brilliantly to create a story you’ll laugh your way through and won’t want to put down, right up to the very unexpected final pages.
Highly recommended for those who loved The Martian, Cast Away, and other lone-survivor stories of sci-fi or adventure, this is a book which will tug at your heartstrings and stretch your imagination to dazzling new heights.
