Weaveworld (Voyager Classics)
Don't let your teenager read this story!!! Big red light warning. I read this book when I was 14 and grew up very quickly! I literally threw up because it was so dark, so graphic and sooo adult!!! But...it changed my life, because it made me question reality, the world woven into the carpet literally amazed me, sickened me, but amazed me all the same! It needs a certificate of 18 in my opinion LOL
