Project Hail Mary

Project Hail Mary is Andy Weir's 2021 science-fiction novel about Ryland Grace, an astronaut who wakes up far from Earth with missing memories and a mission tied to the survival of the planet. About Amazon identifies the Prime Video film as an adaptation of Weir's novel, and Penguin Random House lists the Ballantine Books hardcover with ISBN 9780593135204.

If The Martian made Weir's style familiar, this book gives you the same problem-solving pleasure at a larger scale. The story is built from physics, biology, improvisation, and one of modern science fiction's most reader-friendly first-contact relationships.

Read it before the film if you want the book's discoveries to arrive in your own head first. A screen version can show the spacecraft and the crisis, but the novel's appeal is how each solved problem creates the next one.

Ryland Grace begins as a puzzle to himself. His memory gaps make the science plot and the personal story unfold together.

Rocky changes the book from survival math into relationship-driven science fiction.

Eva Stratt gives the Earth storyline its hard decisions and political pressure.

The Hail Mary crew matters because absence is part of the book's emotional structure.
