The vampire, Cal, offers her an obscene amount of money if Iris will get him out of his house and shelter him until he can heal.

Unbeknownst to the other Council members, he has been brought to the Hollow to investigate a recent rash of vamp-on-human crimes.

As Cal grows stronger, he and Iris become closer as they continue his investigation. But what kind of life can a girl have with the undead?
