Jericho Parker trains dogs to conduct searches of all kinds, sniffing out drugs, explosives, or cadavers. But most of all, he rescues the living. Whenever a disaster strikes, Parker and his Shepherd partner Lucy are ready to locate and save the victims other first responders might never find.

As Parker considers leaving rescue work, he looks back on the people--and the dogs--who helped him find his place in the world. Great challenges lie ahead, and this time the risks are personal. No one else can show him how to escape the past. The new path is one he must pursue alone.
