1991. A restless young man called Dox is back home in Texas. His friends have missed him, and his mother and sisters need him. But after four years as a Marine and another two as a CIA contractor fighting the Soviet Union alongside the Afghan mujahideen, small-town life in Abilene is a suffocating dead end. Another secret war, this one in Southeast Asia, offers a big payday and the solution to his family’s troubles. But secret wars are never what they’re billed to be, and Dox is about to get the education of his young life.

NSA director Theodore Anders has a simple goal: collect every phone call, email, and keystroke tapped on the Internet. He knows unlimited surveillance is the only way to keep America safe. Evelyn Gallagher doesn't care much about any of that. She just wants to keep her head down and manage the NSA's camera network and facial recognition program so she can afford private school for her deaf son, Dash.

Seattle PD sex-crimes detective Livia Lone knows the monsters she hunts. Sold by her Thai parents along with her little sister, Nason; abused by the men who trafficked them; marooned in America...the only thing that kept Livia alive as a teenager was her determination to find Nason. Livia has never stopped looking. And she copes with her failure to protect her sister by doing everything she can to put predators in prison.

When a joint FBI-Seattle Police investigation of an international child pornography ring gets too close to certain powerful people, sex-crimes detective Livia Lone becomes the target of a hit that barely goes awry - a hit that had been offered to John Rain, a retired specialist in "natural causes." Suspecting the FBI itself was behind the attack, Livia reaches out to former Marine sniper Dox. Together, they assemble an ad hoc group to identify and neutralize the threat. There’s Rain. Rain’s estranged lover, Mossad agent and honeytrap specialist Delilah.

Half American, half Japanese, expert in both worlds but at home in neither, John Rain is the best killer money can buy. You tell him who. You tell him where. He doesn’t care about why... Until he gets involved with Midori Kawamura, a beautiful jazz pianist - and the daughter of his latest kill.
