A mother and her eleven-year-old daughter vanish from their Crossfire Creek home. The girl is vulnerable. The mother, impulsive. Tracker Aroostine Higgins is called in to find them, fast, before they're hurt ... or worse.

Aroostine assumes her Rue Jackman alias, packs up her truck, and hits the road with her dog Rufus by her side to do what she does best: Find the missing.

Unofficially, under the radar, and not necessarily entirely legally.

Meanwhile, Special Agent Patton Banks of the National Park Services Investigative Services Branch is tasked with solving the execution-style murder of a low-level criminal.

Officially, entirely legally, and as quickly as possible.

When Aroostine's search gets tangled up with Patton's investigation, the collision sets off a barrage ... and she's caught in the crossfire.
