"On the very night she gets engaged to the man she loves, sex-crimes prosecutor Anna Curtis's professional life takes a shocking turn that threatens everything she holds dear. While Anna is enjoying a romantic dinner capped off by a marriage proposal, a few miles away two separate groups are gearing up to raid a brothel. A vicious killer known as Diablo--the Devil--leads one group. A few minutes later, Anna's own investigative team heads in to search the brothel, as part of the fight against human trafficking in D.C. Both groups are caught off guard, with deadly results. As Anna investigates the bloody face-off, the boundaries between her work and home life begin to blur. Though eager to focus on her new fianc�e, the chief homicide prosecutor Jack Bailey, and her soon-to-be stepdaughter, Olivia, this case and the search for Diablo are never far from her mind. When Anna discovers a web of long-buried secrets and official lies leading straight to her doorstep, the truth about this case threatens to rob her of the happiness she seemed so close to securing. And everything Anna counted on becomes a question mark as Diablo moves in for yet another kill."--Dust jacket.
