Project Hail Mary

Ryland Grace wakes up on a spaceship with no memory of who he is or why he is there. He is alone with two dead crewmates, a computer that interrogates him, and a growing sense that something enormous depends on him figuring out the mission.

As his memories return, the story moves between the present on the ship and the events that led to the mission. Those flashbacks reveal a planetary emergency, an urgent scientific effort, and the impossible chain of decisions that put Grace in space on what amounts to a last-chance run.

In the present, Grace has to survive, understand the science, and keep moving toward a solution. The voyage becomes more complicated when he encounters an unexpected ally in space, turning the mission into not just a struggle to save Earth, but a test of communication, trust, and cooperation across profound differences.
