In this clever and compulsively readable debut, set in a magical analog of Portland, Ore., Allie Beckstrom is a Hound, able to trace a spell back to its caster. When a young boy is injured by a spell, Allie tracks it back to her estranged father, Daniel, a ruthless businessman who protests his innocence. Then someone magically disguised as Allie kills Daniel. Allie and sexy corporate operative Zayvion race against time to find the answers. Magic is common in this alternate universe, but using it always incurs a physical or mental cost, rendering it a commodity to be bought and sold, used and abused.
