The Drum, the Doll, and the Zombie (Johnny Dixon)

A young sleuth and his professor friend fight voodoo, black magic, and a hungry zombie horde . . .
 
The drum is small, no bigger than a plastic cup, and decorated with sun-bleached bones. It is a token from the island of St. Ives, whose voodoo cults are infamous around the world, and it is one of the most dangerous objects Johnny Dixon has ever held. When he raps the little drum, the wind howls, and an explosion rocks the house. There are more surprises to come. An inquisitive young man, Johnny has tangled with all manner of supernatural beasts along with his friend Professor Childermass, and now they will confront the living dead.
 
The drum summons up a whirlwind of black magic and throws one of the professor’s colleagues into a strange trance. To rescue him, Johnny and the professor must defeat an evil sorceress, and send her zombies back to where they belong.
 
From the author of the Lewis Barnavelt novels, including The House with a Clock in Its Walls, the Johnny Dixon series is full of fun, adventure, and supernatural chills, along with “believable and likable characters” who are a delight to spend time with (The New York Times).
