Project Hail Mary

Well, I never thought I'd enjoy a super scienc-y sci-fi this much.

Ryland Grace wakes up alone in a space ship, and he has to figure out how to save Earth. Along the way Spoiler he meets Rocky, an alien from another planet with the same problem as Earth. I absolutely loved Rocky and the relationship he and Grace formed. I also enjoyed the way they approached their communication issues. Just goes to show that we can always figure out a way to communicate with one another. This book was funny, emotional, hopeful and action-packed all at once. As much as I didn't understand the science, it felt plausible and still somehow enjoyable to read, considering there's so much of it. I never knew a sci-fi in space could be such a feel-good story.
