Savage Alliance (The Nickie Series, Book 5) in Bloomington, MN

Duncan has finally found his life's purpose-rescue trafficked children-while Detective Nickie Savage still seeks closure. In Lima, Peru, following a lead discovered on a mole's computer, Nickie and Duncan are undercover as traffickers. The plan: infiltrate the compound. Rescue the children. Blow the place up. Then Nickie goes radio silent. Recognized by the man who abducted her as a child, she's once again in his hands. And this time, escape is not an option.
