In the thrilling conclusion of the "Deadly Secrets" series, dog trainer Keely Lambert breaks in Titan, a new shepherd, during a rescue mission to find little Conner Wells. Aided by childhood friend, Beau Gardner of the TBI and Conner's uncle, Keely finds the boy deep inside Beaman Park.
But Conner is not all that Keely found. On the way back to the welcome center, she notices something sticking out of the dirt—the military dog tags of her father who disappeared more than two decades before.
The discovery sets Keely on a hunt to unearth her father's killer, only to be thwarted by multiple setbacks—the murder of Beau's father, the kidnapping of her mother, and her kennel being set on fire in the middle of the night. After Keely is kidnapped herself, Beau leads a manhunt to find her before the outcome reaches a deadly conclusion.
