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.
