"Retired FBI agent Brigid Quinn knows how difficult it can be to overcome one's past. But she is nothing if not a fighter. Even when the return of a serial killer from her past threatened to derail her new marriage, she managed to hold on to the life she's been trying to build in Tucson with her husband Carlo ... After her sister-in-law dies, Brigid's [seventeen]-year-old niece Gemma-Kate comes to live with her and Carlo ... Brigid doesn't exactly love the idea, especially since there's always been something unsettling about Gemma-Kate, but family is family. Meanwhile, Brigid agrees to help a local couple by investigating the death of their son--until dangerous things start to happen"-- Provided by publisher.
