It has been six weeks since Winter Parish stopped the poisoning of the wood. Six weeks of nightmares, of visions that haunt her even in the light of day. Six weeks of a new intermediary she doesn't trust, no matter how hard he tries to prove himself to her.
Six weeks without Henry.
But when a new threat endangers not only the safety of the wood, but of the entire world, Winter must join forces with unexpected allies, travel through centuries that are not her own, reunite with the boy who holds her heart, and battle an enemy older than time itself, before the very fabric of the universe unravels, leaving nothing in its wake.
