The Shade of the Moon - Susan Beth Pfeffer
Well, this was a "maybe" that I was more than likely going to read, because series. But now that has become a resounding fuck no. I already had a tenuous relationship with this series. The third book messed it up enough. This utterly decimates it. This shit right here is a good part of why I so dislike YA. And I read so few and this still happens.
