AFTER the sudden and mysterious death of their parents, twins Asher & Ember Drake are whisked away from their familiar life in New York City to the secluded town of Willowycke, Maine. Here, under the care of their maternal grandparents, they are thrust into a world that feels both hauntingly familiar and unsettlingly foreign.

In the shadow-draped woods and fog-laden streets of Willowycke, a town steeped in Caster legends and whispered secrets, Asher & Ember begin to unravel the threads of their hidden heritage. They discover that they are descendants of a powerful line of Casters—individuals with the ability to manipulate the very elements themselves—and are tied to a prophecy that foretells great power and great peril.

As they learn to control their emerging abilities, the twins’ quest for the Wonderspark, an ancient artifact of untold power stolen from the primordial fires of Eden, draws them deeper into the mystic. This elusive artifact holds the key to unlocking their full potential and, perhaps, the secrets behind their parents’ untimely deaths.

Navigating a maze of ancient loyalties and new alliances, Asher & Ember must decipher friend from foe. Their search is complicated by the dark forces that seek to capture the Wonderspark for their own sinister ends. With each step closer to the truth, the twins find themselves caught in a web of danger and dark magic, where each revelation brings them closer to the ultimate confrontation.

Bound by blood and a destiny larger than themselves, Asher & Ember must confront not only the shadows lurking outside of Willowycke but also the darkness within themselves. In the battle for control of the Wonderspark, and the power it holds, they will discover that the greatest challenge may be learning to trust in their own strength and each other.
