Signed by the author. A hugely successful modern science fiction novel by Andy Weir, Project Hail Mary combines hard science, humour, suspense, and interstellar adventure in the tradition of the author's earlier bestseller The Martian. The story follows Ryland Grace, a lone astronaut who awakens aboard a spacecraft with no memory of his mission, only to discover that the survival of Earth may depend entirely upon him. Praised for its inventive scientific problem-solving, emotional depth, and memorable first-contact narrative, the novel quickly became one of the most celebrated works of contemporary science fiction. Its profile has risen further with the major film adaptation starring Ryan Gosling, directed by Phil Lord and Christopher Miller, released in 2026 to considerable commercial and critical success.  Project Hail Mary, by Andy Weir.  Published by Del Rey, London. 2021 first UK edition, released simultaneously with the USA publication (4 May 2021), 1st impression.
