A lone astronaut. An impossible mission. An ally he never imagined. Ryland Grace je jediným survivorom on a desperate, posledná šanca misie - a ak nie sú falošné, ľudské a krajiny, ktoré budú perišské. Except that right now, he doesn't know that. Nie je možné remember jeho vlastného mena, rokov sám o prírode jeho assignment alebo how to complete it. All he knows is that he's been asleep for a very, very long time. And he's just been awakened to find himself milióny z miles z domova, s noting but dva corpses for company. His crewmates dead, jeho memories fuzzily returning, Ryland realizuje, že impossible task now confronts him. Hurtling cez priestor na tejto tiny lodi, to je him to hádanka out impossible scientific mystery-conquer a extinction-level smerom k našim špeciálom. A s hodinami, ticking down a neďaleko ľudské, aby sa light-years away, je to, aby to všetko. Or does he? Na irresistible interstellar dobrodružstvo a only Andy Weir môže byť imagine to, projekt Hail Mary je tábor discovery, špecifikácie, a survival k rivalovi Martian - pri tej, ktorá sa berie do priestorov, je never dreamed of going.
