The House With a Clock In Its Walls by John Bellairs
The first book in the Lewis Barnavelt series, this is a supernatural story about a boy who goes to live with his uncle after losing his parents and discovers that his uncle is a real magician. He and his uncle and their next door neighbor discover a clock in the wall of the uncle’s house, put there by the evil magician former owner of the house, that will end the world if they don’t figure out how to stop it first. I really enjoy all of John Bellair’s series – the books are fun – a little scary, but not too much, and the characters are people you would like to know. Lewis and his best friend Rose Rita are my particular favorites. The Lewis Barnavelt series is my favorite, but I also like and recommend the other two series, about Johnny Dixon and Anthony Monday.
