In a last-ditch effort to save Earth from an extinction-level event, a group of astronauts is sent on a desperate mission in a cobbled-together spacecraft. But when Ryland Grace wakes up, he has no memory of his mission or why the rest of the crew is dead. The sole survivor, he must take on an impossible task with no margin for failure.

Andy Weir returns to many of the elements that made The Martian a best seller: a desperate space mission where a sarcastic protagonist MacGyver's his way through with science. Unfortunately, Project Hail Mary doesn't have the mass appeal of The Martian. Ryland Grace is an annoying version of Mark Watney, the mission was less realistic, and the science was overwhelming at times.

I didn't connect with the story until over halfway through and struggled to stay awake through the middle of the book. I would only recommend this book to strong science fiction readers.

I received a complimentary copy of this book from Ballantine Books through NetGalley. Opinions expressed in this review are completely my own.
