From New York Times bestselling author and renowned creator Joey Graceffa comes a pulse-pounding YA fantasy where witches hunt witches, magic has a price, and sisterhood is the only thing standing between light and darkness. Welcome to the coven. Each month, a Zodiac Witch is born, her magic written by the stars. Ophelia and Serena—twin sisters born on the cusp of Pisces and Aries—are trapped in the cold confines of an orphanage until fate rips them from obscurity. Suddenly, they are invited into The Twelve, a powerful coven. To join, they must swear to hunt Dark Witches, creatures of spectral beauty and razor-sharp teeth who survive by siphoning magic from young witches. On a secret island, protected by their new sisters, Ophelia and Serena train to use their powers. Serena commands Lightning, raw and untamed. Ophelia wields Water, quiet and waiting. Their paths shift—one chasing power, the other resisting—as the sisters find themselves caught between two destinies. Some choices can never be undone but they must decide, because magic does not wait, and the darkness is coming for them in ways they could never imagine. After all, the stars never shine without casting shadows.
