For years, Tara Sheridan has been a hermit. She was once a criminal profiler, and a tarot-reading oracle destined for the all-female secret society Daughters of Delphi. After a series of traumas, she left these callings behind and retreated to a remote cabin in the woods. But when a brilliant scientist goes missing amid the ruins of his cutting-edge lab, leaving behind a young daughter, Tara reluctantly agrees to take the case.
This means dealing with the Daughters again, along with a former colleague who makes Tara uneasy.
