Cloister Witte is a man with a dark past and a cute dog. He’s happy to talk about the dog all day, but after growing up in the shadow of a missing brother, a deadbeat dad, and a criminal stepfather, he’d rather leave the past back in Montana. These days he’s a K-9 officer in the San Diego County Sheriff's Department and pays a tithe to his ghosts by doing what no one was able to do for his brother—find the missing and bring them home.

He’s good at solving difficult mysteries. The dog is even better.

This time the missing person is a ten-year-old boy who walked into the woods in the middle of the night and didn't come back. With the antagonistic help of distractingly handsome FBI agent Javi Merlo, it quickly becomes clear that Drew Hartley didn't run away. He was taken, and the evidence implies he’s not the kidnapper’s first victim. As the search intensifies, old grudges and tragedies are pulled into the light of day. But with each clue they uncover, it looks less and less likely that Drew will be found alive.
