Can an officer and his K-9 partner catch a criminal with a deadly plan?

Emergency dispatcher Darcy Lane is abducted and left for dead in a burning house by a vengeful copycat of an arsonist she helped identify years ago. K-9 officer Lucas Harper, the man who once broke her heart, rescues her just in time. Staying one step ahead of a culprit proves nearly impossible, but Lucas will risk everything to keep Darcy safe. With the clock ticking, can they identify who’s terrorising her...before the cold-blooded killer’s long-awaited revenge is complete?
