The series is set in our world—the first two books are set in Tempe, Arizona—where supernatural creatures exist. These include witches, vampires, werewolves, demons, elementals, as well as various deities from many mythologies. The entire series is told in the first-person point of view. In the beginning, the narrative is described exclusively by ancient druid Atticus O'Sullivan (aka. Siodhachan O Suileabhain), owner of the occult bookshop Third Eye Books and Herbs, as he becomes embroiled in the day-to-day struggle of gods, goddesses, and other supernatural creatures.
