The Chestnut King Book 3 of 100 Cupboard by N. D. Wilson

Used. Paperback. When Henry York first knocked on his bedroom wall, he certainly didn't expect to unlock a hundred portals to peril, but N. D. Wilson’s grand finale makes those endless avenues entirely worth the trip. In this concluding chapter, our intrepid Kansas kid must seek out the enigmatic Chestnut King to stop a revived, ravenous witch from eating her way through the multiverse. Wilson weaves wonderfully weird worlds with a deft hand, balancing high-stakes fantasy with grounded family dynamics that keep the magic from flying off the handle.
