Ryder Creed rescues abandoned dogs and turns them into heroes. But this time, it's Creed who may need rescuing when a madman leads him and Agent Maggie O'Dell on a gut-wrenching scavenger hunt.

Sixteen years ago, Ryder Creed's sister, Brodie, vanished from an interstate rest stop. She was only eleven and Creed was fourteen. Her disappearance ripped apart his family and has haunted Creed.

Now a former Marine with his own scars, Creed has dedicated his life to his K9 business. He takes discarded and abandoned dogs and trains them for scent detection. Together they search for the lost and the missing. And always, Creed has held onto the hope that one day he might find out what happened to his sister.

A thousand miles away during a police raid, FBI Agent Maggie O'Dell stumbles upon a clue that may explain what happened to Brodie Creed all those years ago. But to find the answers she'll need to make a deal with a madman. And the search that follows will be as agonizing for Creed, as are the answers he discovers.
