The House with a Clock in its Walls

In 1955, ten-year-old Lewis Barnavelt goes to New Zebedee, Michigan to live with his uncle Jonathan in a creaky old house which has a mysterious ticking heart. Recently orphaned, Lewis only wants to have a normal childhood but soon discovers he's in line for anything but that. Uncle Jonathan is in fact a mediocre but well-intentioned warlock, while his next-door neighbor and good friend Florence Zimmerman is a far more powerful good witch. The house that Lewis has just moved into was previously owned by Isaac and Selena Izard. Before dying, this sinister couple had constructed a powerful clock that is hidden somewhere within the walls of the house where it ticks eternally, trying to pull the world into a magical alignment that would have permitted Isaac to bring about the end of the world.
