All Fools:
Asylum
There are really only 2 character's in this book. Every other character is imagined by Amy, because she is clinically insane. Nick is the only other real character, and although he is a character in Amy's imaginary world, he does not act like her imagined version of him. He is a very clever serial killer, and only keeps her around, so he says, because she is useful. In her head, she is in a relationship with him, and eventually he starts falling for her.
