Once soulmates, the witch and warlock covens of the California coast have been estranged for a century. Raised to hate each other, their teenagers meet in the Solstice Stones, a magical battleground where they draw energy from each other to maintain their balance. 16 year olds Logan and Lily have spent years training for their first Stones…only to discover just days before that the enemy may not be what either of them had thought.
In Witch’s Brew, Lily is torn between her feelings for Logan and her coven’s need to know who—or what—he is. The young lovers race against time, their distrust for each other, and the powerful influence of their elders, to unravel the mystery of their pasts before their future is destroyed.
