The gypsy morph

Eighty years in the future, the United States is a blighted no-man's-land, its government collapsed and its citizens fighting for survival against predators, militias, and hideous mutations. Demons and their minions seek to slaughter the last of humankind. Logan Tom, a Knight of the Word, must protect the world's only hope of salvation and settle a score with the demon that massacred his family, while Angel Perez aids the elvish race marked for extermination.
