I can sum up my impression of Bad Girls Don't Die for you in one word. Scary. And by scary, I mean the creepy kind of scary like the old horror movies. The movies that kind of get in the back of your mind and creep you out when you get out of bed in the middle of the night and your house is dark. CREEPY! Katie Alender, you certainly know how to write a thriller.
Kasey, well, Kasey is what some people I know would call a WLK (weird little kid). She is 13, but she is obsessed with dolls. Not the cute Cabbage Patch type, but the creepy antique kind that seem to stare at you when you enter the room. Alexis worries that this isn't going to bring Kasey out of her shell any time soon, but she feels that Kasey is misunderstood until one day Pepper (I KNOW!), Alexis's nemesis, accuses Kasey of breaking her little sister's arm. Alexis was under the impression that Mimi had broken her arm accidentally while she and Kasey were running in the house. When Alexis questions Kasey about this, something about Kasey begins to change, and change, and change.... Alexis must solve the mystery of a tragedy that happened long ago in their home and forge a relationship with an unlikely ally to try to save Kasey from what seems to be happening to her.
