I love fiction, but some of my favourite books are non-fiction. Some of my favorites are:
Sapiens by YNH: It is hands down one of the most perspective-changing books that I have ever read.
How To Be Miserable by Randy J Paterson. This is an interesting self-help book as it uses reverse psychology to show you strategies that you can use to be happy, by presenting all of the things we do to make us unhappy.
Some others would be Columbine by David Cullen & Heavier than Heaven: The biography of Kurt Cobain, by Charles R Cross. What are yours?
