A high concept thriller and genre busting classic, now a major motion picture starring Matt Damon A survival story for the 21st century and the international bestseller behind the major film from Ridley Scott, starring Matt Damon and Jessica Chastain. I'm stranded on Mars. I have no way to communicate with Earth. I'm in a habitat designed to last 31 days. If the oxygenator breaks down, I'll suffocate. If the water reclaimer breaks down, I'll die of thirst. If the hab breaches, I'll just kind of explode. If none of those things happen, I'll eventually run out of food and starve to death. So yeah. I'm screwed. Andy Weir's new stunning science-based thriller Project Hail Mary is available now.
