Harper is fighting for her life. Her new book is going to put judges and senators in jail for environmental corruption. Wanting her dead before she can publish, they hire an organization of contract killers.

Riker agrees to protect her, but she insists on visiting the crime scenes in her book on her way to her New York publisher.

From the Alaska forest they call the lungs of America, to the swamps of Louisiana, and the deepest part of the Gulf of Mexico, they struggle to stay alive as she gathers proof.

Riker brings her aboard his WW II converted Battle Cruiser to try to keep her safe. But the contract killers find them and attack. Fighting off high-speed attack boats and Blackhawk helicopters, they have little chance of survival.

Their battles are hindered by a complex relationship. Riker refuses to get close to Harper, worried it could distract him enough she could be killed. Harper has little to lose and pursues him. Discover what happens when a determined, talented woman takes on the most powerful people in America.
