The House with a Clock in it's Walls:
"Lewis always dreamed of living in an old house full of secret passageways, hidden rooms, and big marble fireplaces. And suddenly, after the death of his parents, he finds himself in just such a mansion--his Uncle Jonathan's. When he discovers that his big friendly uncle is also a wizard, Lewis has a hard time keeping himself from jumping up and down in his seat. Unfortunately, what Lewis doesn't bank on is the fact that the previous owner of the mansion was also a wizard--but an evil one who has placed a tick-tocking clock somewhere in the bowels of the house, marking off the minutes until the end of the world. And when Lewis accidentally awakens the dead on Halloween night, the clock only ticks louder and faster. Doomsday draws near--unless Lewis can stop the clock!"
