Bad Girls Don't Die: From Bad to Cursed (Google eBook)
Alexis is the last girl you'd expect to sell her soul. She already has everything she needs--an adorable boyfriend, the perfect best friend, and a little sister who's finally recovering after being possessed by an evil spirit, then institutionalized. Alexis is thrilled when her sister joins a club; new friends are just what Kasey needs. It's strange, though, to see how fast the girls in The Sunshine Club go from dorky and antisocial to gorgeous and popular.
