Bad Girls Don't Die is the first book in the Bad Girls Don't Die Series. This book introduces many characters.
When Alexis' little sister, Kasey, becomes obsessed with this antique doll, Alexis thinks nothing of it. Kasey is a wierd kid. Period. Alexis is considered wierd, too, by the kids in her high school, by her parents, even by her own goth friends. Things get wierder though, when the old house they live i starts changing. Doors open and close by themselves, water boils on the unlit stove, and the unplugged air conditioner turns the house cold enough for the girls to see their breath. Kasey is changig too. Her blue eyes go green, and she uses old-fashioned language, then forgets chunks of time.
Most disturbing of all is the dangerous new chip on Kasey's shoulder. The formerly gentle, doll-loving girl is gone, and the new Kasey is angry. Alexis is the only one who can stop her sister - but what if the green-eyed girl isn't even Kasey anymore?
