Gypsy morph. Terry Brooks. 2009.

The last cities have fallen. Demons and once-men swarm the ravaged landscape of the former United States. A small band of survivors - the elves of Cintra and a ragtag group of human children and their protectors - flees northward toward a safe haven. To reach it, they must follow the boy named Hawk - now revealed as the gypsy morph.

The brave remnant faces attacks on all sides. At stake are the survival of the two races - human and elf - and the beginning of a new world for both.
