Holly Summers is deaf, but she "hears" thanks to her immense talent for lip-reading. A child welfare officer, Holly moonlights for the Portland, Oregon, police, using her unique gift to aid in criminal investigations -- including one into the case of a recent string of women who have vanished without a trace.

Witnessing unimaginable evil in the abuse cases she handles, Holly fights every day to salvage broken young lives. But her good works spark plenty of enemies; someone has targeted this avenging angel with a supernatural vow to harm her. And the terror begins when Holly's young daughter disappears.

Fending off the shadows of an unearthly predator and the very real threats facing a woman in a man's world, Holly must listen to her deepest instincts for survival -- to save the one person for whom she is living.
