The Rabbit Hole

By yours truly! 
Because I’ve been really getting into philosophy/philosophical reading, some of these suggestions might also have a paired philosophy book/deep dive keywords if that’s something you're into because I’m evil and I want to get you sucked into the hole too. Obviously only if you feel like it! But I’m just going to throw it out there just in case. Personally, if you’re going to deep dive, I suggest actual internet rather than a book because the books can be a bit uh long and fat and overwhelming. 
Also if you want more depressing books I definitely have them. Some of these are sad, but like I also have SAD if you happen to want to bawl on a random Tuesday.
