On the island of Alapora, only the elite and wealthy priests and priestesses, known as the Holy Ones, are permitted to safely use the magic of demons, but that doesn't stop the common people, or the demons. For years, demons and humans have been mingling in the mysterious Masked Market, where demon magic is traded in secret.
One day, Zomoc, the overeager student of a powerful priestess, seeks out the Masked Market to investigate, and meets a girl named Mola. The two become involved in a shocking chain of events that unravels everything Zomoc thought she knew about herself and her home.
Over the next three years, Zomoc and Mola give everything they have to spearhead a movement to use magic to take down the Holy Ones...or die trying.
