Lewis Barnavelt, after losing his parents, is sent to Michigan to live with his uncle Jonathan. He discovers his uncle is a warlock, and enters a world of magic and sorcery. But this power is not limited to good people: Lewis learns of Isaac Izard, an evil wizard who constructed a magical clock with black magic, as long as it exists it will keep ticking, counting down to doomsday. He died before he could finish the clock, but he hid the clock in his house, where Uncle Jonathan now lives. Now Lewis and Jonathan must find the clock before it finishes its countdown and ends the world.
Jonathan's last name is Barnavelt, the same as Lewis. But Jonathan is Lewis' mother's brother, and his last name should be her maiden name, not Barnavelt. The only ways they both could be named Barnavelt would be if her husband's name also just happened to be Barnavelt, or if the family used a naming convention that was extremely unusual and nonconforming by the standards of 1940s-1950s America.
