My favourite thing about this book is that all the characters kinda sucked. To put it plainly, most of them were shitty people in one way or another. Because this story is told from their perspectives, you get to see their inner thoughts and why they do what they do. You get to read about the groggy next day thoughts of an alcoholic who blacked out, the victim complex of a woman not quite right in the head, and more. It's fascinating.
