Evelyn Brooks lives with the freedom only her kind can know-in her human form as a photographer, and in the skies as a peregrine falcon. When a stalker drives her from her home, Evelyn discovers a beautiful, wild sanctuary in North Carolina. After a bolt of magic knocks her from the sky, leaving her helpless, she realizes too late that danger has invaded her refuge. Park ranger Lawke Morgan's day goes from bad to worse when his ex-wife unexpectedly drops off their 13-year-old daughter, Zoe, in the beginning of a dangerous storm. His life takes a turn for the bizarre after he finds an injured Peregrine falcon that transforms into a lovely woman. When his daughter is kidnapped by an Aztec priest, one who should have been dead for centuries, Lawke learns that Evelyn holds the key to the priest's demands. Together they must confront blood sacrifices, defy ancient gods, and find a way to trust each other when Zoe's life hangs in the balance.
