Lucas Davenport's adopted daughter, Letty, is home from college when she gets a phone call from a woman Traveler she'd befriended in San Francisco. The woman thinks somebody's killing her friends, she's afraid she knows who it is, and now her male companion has gone missing. Letty tells Lucas she's going to get her, and, though he suspects Letty's getting played, he volunteers to go with her....

Lucas Davenport's first case as a US marshal sends him into uncharted territory in the thrilling new novel in the number one New York Times best-selling series. Thanks to some very influential people whose lives he saved, Lucas is no longer working for the Minnesota Bureau of Criminal Apprehension but for the US Marshals Service, and with unusual scope. He gets to pick his own cases, whatever they are, wherever they lead him.

The daughter of a US Senator is monitoring her social media presence when she finds a picture of herself on a strange blog. And there are other pictures...of the children of other influential Washington politicians, walking or standing outside their schools, each identified by name. Surrounding the photos are texts of vicious political rants from a motley variety of radical groups. It's obviously alarming - is there an unstable extremist tracking the loved ones of powerful politicians with deadly intent? But when the FBI is called in, there isn't much the feds can do.

Bonnie and Clyde, they thought. And what's-his-name, the sidekick. Three teenagers with dead-end lives, and chips on their shoulders, and guns. As their crime spree cuts a swathe through Minnesota, captured on the killers' cell phones, and sent to a local television station, Investigator Virgil Flowers joins the growing army of cops trying to catch them. But even he doesn't realise what's about to happen next.

Lucas Davenport has had disturbing cases before - but never one quite like this, in the shocking new Prey work from the #1 New York Times best-selling author.
