"Twenty-one days. In a world ravaged by fire and descending into madness. Cavalo has been given an ultimatum by the dark man known as Patrick: return Lucas to him and the cannibalistic Dead Rabbits, or the town Cottonwood and its inhabitants will be destroyed.

Twenty-one days. Cavalo has twenty-one days to prepare for war. Twenty-one days to hold what is left of his shredded sanity together. Twenty-one days to convince the people of Cottonwood to rise up and fight back. Twenty-one days to unravel the meaning behind the marks that cover Lucas. A meaning that leads to a single word and a place of unimaginable power: Dworshak"--Back cover.
