Philoxenia. When the police call using this code word, 16-year-old Darya knows she will be sheltering strangers. Nonhumans seek Darya's protection too, whispering from the depths of the forest in voices only she can hear. If she obeys the voices, she risks her adoptive mother's rage, the taunts of a surly island boy, and the wrath of her community. If she refuses the voices, a primeval species faces extermination.
