Book excerpt: USA TODAY bestselling author Jeff Hirsch once again creates a futuristic world with stunning, dramatic realism. A civil war rages between the Glorious Path--a militant religion based on the teachings of a former US soldier--and what's left of the US government. Fifteen-year-old Callum Roe and his younger brother, James, were captured and forced to convert six years ago. Cal has been working in the Path's dog kennels, and is very close to becoming one of the Path's deadliest secret agents. Then Cal befriends a stray dog named Bear and kills a commander who wants to train him to be a vicious attack dog. This sends Cal and Bear on the run, and sets in motion a series of incredible events that will test Cal's loyalties and end in a fierce battle that the fate of the entire country rests on.
