Project Hail Mary

Ryland Grace wakes up on a spaceship with no idea who he is or how he got there. He is millions of miles from Earth, and his two crewmates are dead. As his memory slowly returns, he realizes he is the sole survivor of a last-chance mission to save humanity from an extinction-level threat.

The sun is dying, and if Ryland can’t solve the scientific mystery behind it, everyone on Earth will perish. Alone in the deep silence of space, he must use his wits and scientific knowledge to fix his ship and find a solution. However, the task is nearly impossible for one person.

Just when things seem most desperate, he discovers he might not be as alone as he thought. This thrilling adventure is a race against time, filled with humor, "cool science," and a surprising story of friendship that spans the stars.
