Distracting Books

My friend is dealing with some medical things and is looking for some distracting books to read to help keep their mind off of things.

Genres they like: SciFi, Dystopian, Fantasy, Mystery (fiction in general)

Titles they've enjoyed: Brave New World, Space Odyssey, Rabbits, Ready Player One

I also just shared the first chapter of If This Book Exists You're In The Wrong Universe, and they enjoyed that as well.

Books need to have a fairly quick hook in order to grab them. I would really appreciate any recommendations you have. Thank you so much.
