Arthur is safe, but his world is not. Along with the key comes a plague brought by bizarre creatures from another realm. A stranger named Mr. Monday, his avenging messengers with bloodstained wings, and an army of dog-faced Fetchers will stop at nothing to get the key back, even if it means destroying Arthur and everything around him.
Desperate, Arthur ventures into a mysterious house, a house that only he can see. It is in this house that Arthur must unravel the secrets of the key, and discover his true fate.
Keys to the kingdom is a fantasy thriller, that takes place two worlds. The land of reality which we all know to well, and the land of house, where time is controlled by the wealthy, and feared by the poor.
