Three devious prisoners vow murderous revenge.
Now the first is free.

It was inescapably chilling, as if the murderer was methodically working his way down a page torn from the phone book.

Aidan has been out of commission since an undercover operation went bad more than a year ago. Back on the job, his razor-sharp instincts are returning. But it will take all of Aidan's wits to stay one step ahead of the elusive killer who has engaged him in a deadly game--a game in which Mara's life is the prize. A game only one can win . . .
