1969: a Navy SEAL, a trained assassin on a confidential mission, is dropped off in the Vietnam jungle. Days later, a U.S. gunboat returns to pick him up, but the boat's young captain panics under fire and leaves the SEAL behind. Twenty years later, that young captain is now a Pentagon admiral as the SEAL returns to Washington, D.C. with his own career change: he's become a sweeper--a clandestine cleaner of secret messes. And he's come back to claim "some things of value"--things the admiral can't afford to lose. Navy Commander Karen Lawrence--sharp, smart, and savvy--is assigned to investigate the bad things that start happening to the admiral. She finds herself caught between one man's boundless ambition and another's relentless quest for revenge.
