About the book

Project Hail Mary is a science-fiction novel by Andy Weir in which Ryland Grace, a former scientist turned schoolteacher, wakes alone aboard a spacecraft with no memory of who he is or why he is there. As his memories return, he learns that the Sun is being dimmed by a single-celled organism called Astrophage, threatening all life on Earth, and that he is the last surviving crew member of a desperate interstellar mission to the star Tau Ceti to find a solution. Stranded light-years from home, Grace must rely on improvised experiments, hard science, and an unexpected encounter to give humanity a chance.

Like Weir's earlier work, the book is built around problem-solving, scientific reasoning, and survival under extreme conditions, leavened with humor. Its central themes include cooperation across difference, sacrifice for a greater good, and the power of curiosity and friendship in the face of an existential crisis. The story alternates between Grace's present-day predicament in deep space and flashbacks to the coordinated global effort to confront the Astrophage threat.

Project Hail Mary was published in 2021 to strong commercial and critical success, debuting high on the New York Times bestseller list and spending many weeks there. It won the 2021 Dragon Award and Goodreads Choice Award for Best Science Fiction and was a finalist for the 2022 Hugo Award for Best Novel, while Ray Porter's audiobook narration was widely praised. A major feature-film adaptation followed in 2026.
