Fiction: Romance 
The Fault In Our Stars by John Green: Yes, yes I know. What kind of white girl fuckery is this? But hear me out guys. While this may be a very "mainstream" book that basically everyone has heard of and knows the plot to, it is the single most inspiring, heart wrenching, beautiful pieces of fiction I have ever had the pleasure of reading. When I first started reading I expected this to be your typical romance novel, but it is anything but that. It has adventure, it makes you laugh, cry, question your existence, and help you find a little bit of beauty in this cruel, cruel world. 10/10 recommend, I've personally read it at least 8 times by now, it's amazing. The main character is so sarcastic and relatable, they make fun of the cliches, it's beautiful.
