Colorado K-9 Rescue

Book One

A kidnapper’s twisted game is on.
And a trusty K-9 won’t let him succeed.

Years after being abducted, Mckenna Parker’s worst nightmare has come true—her kidnapper is out on parole. And he’s after her again. Now an FBI victim specialist, she and her crisis canine, Mocha, have been assigned to a case with FBI agent Evan Knox. Together they must find two local girls who disappeared. As passionate as Mckenna is about helping others, Evan is ambitious about his career. Both have sworn off love. But when Mckenna vanishes into the mountain wilderness, it’s Evan—with Mocha’s amazing help—who braves danger at all costs.

Kathleen Donnelly delivers a gripping mix of romantic suspense and canine heroics in Colorado K-9 Rescue, a story that is equal parts heart-pounding thriller and tender love story…With its vivid Colorado setting, strong emotional core, and authentic K-9 details, this is a standout romantic suspense novel—perfect for fans who crave both danger and heartfelt connection.
