From the publisher:
Hidden cupboards behind Henry's bedroom wall unlocked portals to other worlds that Henry and his cousin Henrietta couldn't resist exploring. But they made one terrible mistake--they released the undying witch Nimiane. Her goal? To drain all life from every world connected to the cupboards. Henry must seek out the Chestnut King to defeat her, but doing so will force Henry to make a terrible, irreversible choice. With the fate of the worlds and everyone Henry loves hanging in the balance, will he have the courage to do what is needed to destroy the witch once and for all?
