From #1 New York Times bestselling author Robert Beatty comes a spooky, thrilling new series set in the magical world of Serafina. Move without a sound. Steal without a trace. Willa, a young nightspirit of the Great Smoky Mountains, is her clan's best thief. She creeps into the homes of day-folk in the cover of darkness and takes what they won't miss. It's dangerous work—the day-folk kill whatever they do not understand. But when Willa's curiosity leaves her hurt and stranded in a day-folk man's home, everything she thought she knew about her people—and their greatest enemy—is forever changed.
