   Summary

   Eight years after Ryland Grace disappeared from your life, he calls you out of nowhere with a problem: an alien microorganism is dimming the Sun, and he thinks you can help.

   Now you're working beside the man who used to be your best friend—and trying to understand an organism that shouldn't exist before it helps end life on Earth.

   A canon-divergent retelling of Project Hail Mary featuring a microbiologist Reader whose expertise, history with Ryland, and place on the project change the course of the mission.
