A story about a high school science teacher who gets sucked (willingly) into humanity's attempt to save itself from "astrophage", a microbe that has the capability of living on the surface of the sun because it lives on energy. The problem is that astrophage will dim the sun by 10% and that will kill everyone.
The story begins with Ryland Grace waking up on a space ship with no memories. The device allows Weir to go into the history of astrophage through flashbacks, and also allow some things to not be told to the reader because Grace doesn't remember them... yet. Anyway, Grace realizes he's at Tau Ceti because it's the only nearby star system that isn't infected with astrophage and he's there to figure out why.
Project Hail Mary has a very 80s feel to it. Very gee whiz exploring the universe is very cool. A lot of plausible sounding science, if you accept the premise that a microbe can absorb the sun's energy, store it, and then propel itself at nearly the speed of light through releasing that energy.
Most of the characters appear in flashbacks explaining how we got here, and those characters are fun caricatures. Unfortunately only one of them, Eva Stratt gets any real repeat scenes. She's the administrator who is put in charge of Project Hail Mary. A wondrously amoral character that can command the militaries of any of the world's powers, including detonating nukes in Antarctica and force-drafting scientists to the project who really don't want to be part of it.
The primary story happens on the Hail Mary in the Tau Ceti system with Grace alone trying to figure out what to do. The plot is a series of scenes of problems appearing, Grace thinking and sciencing his way through them, followed by a short respite or flashback before the next problem appears. Grace solves all of them, but this isn't competence porn. He's incredibly sloppy in a way that really does remind me of my high school science teachers.
This is clearly written to be a major motion picture or a streaming series, so I expect there will be ample opportunity to consume this story that way soon.
