When Olivia Doyle's father dies under suspicious circumstances, rather than inheriting a family fortune, she inherits a new identity. She learns they were placed in the Federal Witness Security Program when she was five years old. Her father was involved in an art forgery ring and testified against the mob. Brought up not to trust anyone, Olivia has a difficult time relying on U.S. Marshal Ethan Ryder to protect her, and to keep her secret. She fears her father may have continued his life of crime through her art gallery. She has little choice but to depend on Ethan when she realizes someone is now after her. Olivia's search for the truth leads her and Ethan across the country to a family and a past she doesn't remember.
At the age of ten, Ethan witnessed a brutal murder. He vowed that when he grew up, he'd protect people in danger. Protecting Olivia is difficult when she won't trust him. He soon realizes his desire to protect her goes beyond doing his job, but if his judgment becomes clouded by emotions, her safety could be jeopardized.
Can Ethan and Olivia learn to trust each other when they uncover secrets that will change their lives forever?
