Small-town librarian Ophelia Jensen is finally starting to embrace her lot as one of the "chosen"—a psychic and folk magick practitioner, a.k.a. a witch. Expert loving guidance from her magickally adept grandmother Abby helps—and adopting Tink, an exceptionally talented teenage medium, has given Ophelia's life new purpose... until a brutal murder clouds the sunshine of their days.

Ophelia's co-worker and best friend, Darci, is distraught when her cousin is implicated in the small Iowa town of Summerset's most recent murder—the violent death of a biker. Unfortunately for Darci's cousin, it's her fingerprints all over the murder weapon. She claims she's innocent, but it'll take Ophelia and Abby more than a good incantation or two to get to the bottom of this crime—what with ghosts, crooked cops, secret identities, and a small army of outlaw bikers thrown into this devil's brew.
