#1 New York Times bestselling author Iris Johansen turns up the heat in this explosive new psychological thriller. This time a gifted arson investigator teams up with a mysterious operative to stop a killer raging completely out of control.

For Kerry Murphy, the inferno is never far away. The flames of that long-ago night still burn in her nightmares: the heat, the choking smoke, the helplessness. She can never run fast enough...

Now Kerry works as an arson investigator with her evidence-sniffing dog, Sam. Together they're a great team, but only Kerry knows the real reason that they're so good at what they do—only Kerry and someone from a past she thought she'd put far behind.

But all that is about to change in the time it takes to strike a match. Suddenly the flames of her past are back, and this time Kerry may not be able to put them out. From out of the ashes of another tragedy a stranger appears. Who is Silver? And why does this mysterious man need her help? Even more disturbing, how does he already know so much about her? All Kerry is certain of is that he's come to enlist her in the hunt for a psychopath who has left a trail of gruesome, fiery deaths in his charred wake—a human monster determined to bring his own private version of hell to earth.

But the killer Kerry is supposed to find has already found her—and in his twisted thoughts and burning obsessions, the nightmare of her own past threatens to ignite and destroy her. When tragedy strikes, Kerry's one hope is Silver: a man who seems to have no alliance to anyone and no authority to answer to—a dangerous man who seems to know Kerry's mind almost as well as she does herself.
