Andy Weir

Andy Weir's Project Hail Mary wakes a man on a spaceship with no memory, no living crew, and a job that decides whether humanity survives. It's hard SF built as a survival puzzle, an amnesia story used as a working engine rather than a hook, and it's warm in ways the genre rarely manages.

An astronaut stranded alone on Mars has to science his way back to life one improvised problem at a time, and the result is the rare survival story that makes competence itself feel thrilling.
