Project Hail Mary — Collector's Edition

Ryland Grace is the sole survivor of a last-ditch mission to save humanity.
But he doesn't know it. He doesn't even remember his own name, let alone the mission's purpose or how to complete it.
All he knows is that he's been asleep for a very, very long time. And that he's now millions of kilometres from home, with two unknown corpses for company.
With his crewmates dead and his memories only vaguely returning, Ryland realises he has an impossible task ahead of him. Time is not on his side and, to avert catastrophe, he must solve a scientific puzzle of epic proportions — and save the human race from extinction.
With other humans light-years away, he has to do it alone. Or does he?
An irresistible interstellar adventure, just as only Andy Weir could imagine. Project Hail Mary is a story of discovery and survival that transports us to places we never dreamed of going.
