The Medusa Files, Case 11: Fallen Stone

Morgan doesn't know how everything went so wrong. Once she was a United States Marshal; now she's a fugitive wanted by the Kin's High Council. She doesn't want to get her human friend involved, but Kate is more likely to know a place to hide that doesn't have a Kin connection, making it harder for the council to find her. Except everything she's learned about not getting caught while hunting fugitives never took magic into account.
