A series of random deaths. A search dog with a nose for trouble. And two teenagers threatened by a mystery they're determined to unravel.

18-year old Bryce Finn is the youngest Search and Rescue dog handler in Washington state. And thanks to the extraordinary nose of his golden retriever Sierra, he's also one of the best. When Sierra sniffs out a possible crime scene during a routine potty break, Bryce trusts his dog--and reports the discovery to law enforcement.

At first, the hit-and-run Sierra uncovers looks like just another in a series of accidental deaths. But as Bryce and Sierra, along with Bryce's girlfriend Katie and her search-dog-in-training Magnum, follow a trail of bodies from the Washington wilderness to a rushing river to a homeless camp, their suspicions grow. Is there some connection between these unexplained deaths? And if there is, can Bryce and Sierra sniff out the killer before the killer finds them - especially with the worst detective on the force questioning their every move?

Packed with action, adventure, and more than a little puppy love, PAYOUT will keep you guessing until the explosive final moments.
