Woah, that was intense!

I absolutely could not put this book down. I constantly wanted to know what had happened, what would happen, and whether or not it had actually happened. The balance between the two characters was perfect; Nick, the nice if useless guy who has the potential to be awful, rude and callous; and Amy, the psychotic, manipulative woman, who is just human enough for everything she does to be believable. The first half of the book was Amy manipulating Nick; the second half Nick manipulating Amy; and the epilogue section, them each manipulating each other into who they wanted them to be. By the end, I felt that they each actually wanted a 'perfect' spouse, but didn't know how to get that without coercing the other into that role.
