Andy Weir is back with a new sci-fi/near future story.

Ryland Grace wakes up with no recollection of where he is and why he's there. It turns out he's on a space ship with a mission to save earth.

I don't want to spoil the story, so it's hard to say much more about it, however, rest assured it has many of the same elements that The Martian has. If you enjoyed that one, you will definitely enjoy Project Hail Mary.

So why does this book get one star less? It's mostly because of the first third of the book. Although it's an interesting part, it does drag on a bit too long for me. It shows that Weir really enjoyed thinking through how that situation could be resolved if it really happened (Encountering an alien species and trying to communicate with it). For me, it took a bit too long.

However, after that setup, the story really gets going and I rushed through the pages, wondering how Grace would get out of the trouble he got into and if he could save the earth.
