Andy Weir is a California science-fiction writer and former software engineer whose work pairs technical problem solving with survival suspense, humor, and optimism. His books include The Martian, Artemis, Cheshire Crossing, and Project Hail Mary.
Ryland Grace wakes aboard a spacecraft millions of miles from Earth with no memory of his identity or mission and two dead crewmates beside him. As his memories return, he realizes he is the sole survivor of a last-chance effort to prevent an extinction-level disaster on Earth. He must reconstruct the mission and solve a scientific mystery with limited time and no nearby human help. An unexpected encounter changes both the problem he faces and the possibility that he may not have to solve it alone.

More About Andy Weir
Andy Weir spent two decades in software engineering before the success of The Martian made full-time writing possible. A lifelong enthusiast of spaceflight, orbital mechanics, and relativistic physics, he brought those interests into fiction built around practical problems and high-stakes survival.
Weir connects his method to programming: he breaks a large narrative problem into smaller steps and solves them in sequence. His interviews also emphasize extensive research and calculation, but the resulting novels use humor, suspense, and human connection to keep the technical material embedded in story.
The Martian, Artemis, and Project Hail Mary extend that problem-solving approach across Mars, a lunar city, and an interstellar mission, while Cheshire Crossing applies his storytelling to a graphic collaboration with Sarah Andersen. Critical reception of Project Hail Mary singled out its tension, twists, scientific speculation, and friendship narrative.
Project Hail Mary also became a significant audio and screen work. Its audiobook won two 2022 Audie categories, including Audiobook of the Year, and the novel was adapted into the Phil Lord and Christopher Miller feature released in March 2026.
