Rookie agent Holland Tylo's Secret Service job is a sanctuary from the tragedy that almost destroyed her 15 years ago. But when Senator Charles Westbourne is brutally murdered on her watch, she's got nowhere to hide.

Desperate to clear her name and tormented by guilt, Holland searches through a computer diskette the senator secreted with her, and unearths a terrifying conspiracy of scandal, blackmail and murder. A shattering attack at her Georgetown townhouse forces Holland to flee from a twisted, brilliant killer, who wants the diskette as he wants her life -- and from her own colleagues, whose motives she can no longer trust. But as the assassin's grisly swath of terror threatens to reach the president, Holland grabs at one last chance to redeem herself -- and Days of Drums races to its electrifying conclusion.
