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 her life is about to change in the time it takes to strike a match. The deadly flames of her past are back, and from out of the ashes a stranger appears. Who is Silver? And why has he chosen her in the desparate race to find a killer determined to ignite hell on earth? Kerry and Silver may not have a chance against a psychopath as coldhearted as his method is red-hot. To save themselves and the innocent lives at stake, Kerry will have to do what she hoped she'd never have to do: fight fire with fire.
