October 2022,330 years after the end of the Salem Witch Trials. Alicia, a young aspiring writer, discovers her ancestor is Tituba, the first woman accused during the trials. After an attempt to cast a spell goes wrong, Alicia tries to go to Salem for answers. Instead, a mysterious stranger takes her to a different Witch City: Crone's Cross. There it is Samhain, the time of year when malevolent spirits are set free, and a conflict is brewing between two covens.

Alicia takes the name of Aradia, the mythic daughter of the Moon Goddess. In Crone's Cross she is accused of being a Witch Hunter, and is forced to be on the run. With the help of three teenaged Bad Witches, Frankenstein's Bride, and even the legendary witch Baba Yaga, Aradia must find a way to survive the city, and find herself in the process.

The true meaning of Samhain is sacrifice, and Aradia may be forced to make a terrible one . . .
