I recently read The Spider & The Fly. It's about serial killer Kendall Francois and this journalist, Claudia Rowe, who was obsessed with him. It's true crime.
I'm currently reading 13 Reasons Why. I've never seen the TV show but I'm thinking about watching it when I finish the book. The tapes kinda remind me of Randy Stair's (Weis Market Shooter) suicide tapes. If you're into true crime, I recommend researching him.
