Please don’t judge me!
This answer is going to get people all annoyed, but New Moon by Stephenie Meyer made me cry. And it wasn’t because it was such a horrible book. I was still recovering from a bad breakup, where I had decided that I was able to move on while talking to the guy who snapped my heart in half. Reading this book, knowing I felt a lot like Bella did (although not codependent and suicidal without him) for Edward, I just sobbed like a b**** when he broke up with her. And then I cried like a b**** again when they got back together in Volterra.
