His ruthless quest to seize their house and its power has put not only the family, but all of mankind, in grave danger. Somehow, the key to everything hinges on Uncle Jesse’s words: “Fixing time is what our family was made to do.” But how can they fix a world turned upside down—much less find their way home? At long last, the secrets of the house and the King family are revealed in the stunning conclusion to this epic series. “If you like creepy and mysterious, this is the house for you! Every room opens a door to magic, true horror, and amazing surprises. I loved wandering around in these books.
