Artemis

Ever had a bad day? Try having one on the moon...WELCOME TO ARTEMIS. The first city on the moon.
Population 2,000. Mostly tourists.
Some criminals.
Jazz Bashara is one of the criminals. She lives in a poor area of Artemis and subsidises her work as a porter with smuggling contraband onto the moon. But it's not enough.

So when she's offered the chance to make a lot of money she jumps at it. But though planning a crime in 1/6th gravity may be more fun, it's also a lot more dangerous.
When you live on the moon, of course you have a dark side...

Project Hail Mary

A lone astronaut must save the earth from disaster in this ‘propulsive’ (Entertainment Weekly), cinematic thriller full of suspense, humor, and fascinating science—from the author of The Martian.

Ryland Grace is the sole survivor on a desperate, last-chance mission—and if he fails, humanity and the earth itself will perish.

Except that right now, he doesn’t know that. He can’t even remember his own name, let alone the nature of his assignment or how to complete it.

All he knows is that he’s been asleep for a very, very long time. And he’s just been awakened to find himself millions of miles from home, with nothing but two corpses for company.

His crewmates dead, his memories fuzzily returning, Ryland realizes that an impossible task now confronts him. Hurtling through space on this tiny ship, it’s up to him to puzzle out an impossible scientific mystery—and conquer an extinction-level threat to our species.
