Willow is a mistake. Ever since she was born she was called a mistake. Growing up she had no one to turn to, no one to love. She has been living alone on the streets for about 10 years and now she is sixteen. She lives in trees and stays by herself. She thinks she is nothing and no body could ever like her. She thinks she's a mistake. The reason why? She was born of Greek god parents which were never supposed to be together. She was taken care of until she was five but then got sent to camp half-blood. No one talked to her because of who she was, so she ran away and has been living on her own since. But a new demigod has entered her life and wants her to come with them. Will she go back to that horrible place, camp half-blood? Will anyone know who her parents are? Will this change her life? See what happens in this book, "Mistake".
