Query: it's a pretty messed up book

Even though it's filled with violence, destruction, and [stomach turning] passages, I surprisingly enjoyed reading "Coin Locker Babies." It is the life story of 2 babies, Kiku and Hashi, who were abadoned in train staion coin lockers. They grow up together and then eventually go separate ways, both living rather messed up lives, but through it all they are searching for something to set them free. With intriguing characters like a beautiful girl with a pet crocodile and an action-packed plot depicting men's desire to destroy and men's will to live all at once, this book will keep you thinking and entertained even if you get grossed out from time to time.
