On what is supposed to be a quiet long weekend in New Hampshire, Deputy U.S. Marshal Mackenzie Stewart is viciously attacked at the lakefront cottage of her friend, federal judge Bernadette Peacham. Mackenzie fends off her attacker, but he manages to escape. Everything suggests he's a deranged drifter--until FBI special agent Andrew Rook arrives.
With Rook, Mackenzie broke her own rule not to get involved with anyone in law enforcement, but she knows he isn't up from Washington, D.C., to set things straight between them. He's on a case.
As the hunt for the mysterious attacker continues, the case takes an unexpected turn when Mackenzie follows Rook back to Washington and finds that Bernadette's former mentor, a once-powerful, now-disgraced judge who has been providing Rook with information, has gone missing. Mackenzie and Rook realize the stakes are higher than either had imagined, and a master criminal with nothing left to lose is prepared to gamble everything.
