Six years ago, witness protection marshal Roland Larson did the unthinkable: he fell in love with a protected witness, Hope Stevens, whose testimony was to put away prominent members of the Romero crime family. When Hope's plan to “cut and run” is interrupted by both the government and the mob, she disappears into a new identity, taking with her not only her testimony but a secret never shared with Larson. Larson, who has been looking for her ever since, is put back on her trail when the Romeros intercept the master WITSEC list from the Justice Department and Hope is believed among the first protected witnesses to be targeted for execution. In a series of terrifying encounters, Larson matches wits with a brutally ingenious killer whose sole target is Hope Stevens.
