New to the seaside town of Rock Cove, first-grade teacher Andrew Knight is intrigued by chatty but sensitive Lucas and his captivating mother. Andrew knows he shouldn’t cross the line with a student’s parent, yet he can’t shake the feeling that the Daltons are hiding something extraordinary.

When dark, lifeless patches begin appearing throughout the forests surrounding Rock Cove, Sierra should be the coven’s best hope. Instead, years away from magic have left her rusty, and every attempt to stop the spread of these magical death zones ends in failure. When her friend Jenna reveals a long-hidden prophecy foretelling a coven fated to stop the rise of the Harbinger, Sierra realizes these disturbances are only the beginning.

With her son in danger, her powers faltering, and a darkness awakening, Sierra must reclaim her magic before the Harbinger rises—and Rock Cove pays the ultimate price.
