He strikes without warning.... He kills without mercy.... He's only just begun....

Iris Johansen, the New York Times best-selling author of The Killing Game and The Face of Deception, delivers a gripping new novel of breathtaking suspense and explosive adventure. It is the story of a courageous woman who is coerced into tracking down a ruthless killer - but as she hunts out her prey with stunning accuracy, she becomes the object of his wrath....

As part of an elite K-9 search and rescue team, Sarah Patrick and her golden retriever, Monty, have a gift for finding what no one else can - whether it's a survivor buried alive by an earthquake or the skeleton of a murdered child. But their latest assignment is not like the others. This time, Sarah is being forced to take part in a deadly mission...by a man who knows enough about her past to ensure her cooperation. A man who won't take no for an answer.

John Logan is used to getting what he wants, and what he wants now is Sarah's help. His top-secret venture has been sabotaged, its facilities destroyed, and its handpicked staff massacred. The sole survivor is being held for ransom. Logan knows that the only way to save the man - and the secrets he holds - is to find him as soon as possible.

Smart, tough, and uncompromising, Sarah is furious when she is strong-armed into joining Logan on his search. And once she takes the perilous assignment, she realizes that Logan's promises that she and Monty will be safe may not be enough to protect them.

Because a killer is devising a sadistic vengeance...and he may soon find use for Sarah.

Racing against time to stop the bloodshed before more victims are claimed, both Sarah and Logan will look straight into the heart of true evil. And when the killer's search for revenge finally ends, no one will ever be the same again....
