This book is about a girl, Ari Selkirk, that always stood out with her long, silvery white hair and strange teal eyes; she always got attention but not in a good way. Growing up in the foster system made Ari tough and untrusting, due to all the abuse and neglect she endured at the hands of her foster families. At least until she met a couple that are bounty hunters and teach Ari how to defend herself, making her a part of the family business.
A few months before her 18th birthday, Ari sets off to a psychiatric hospital where her real mother spent her final days to find out whatever she could about the mother she lost too soon, the father she never knew and who (or what) she really is.
It is not until later on that she realizes that some truths are too haunting, too terrifying, to ever be revealed.
