Aunt Maria by Diana Wynne Jones

In Cranbury-on-Sea Aunt Maria rules with a rod of sweetness far tougher than iron and deadlier than poison. Strange and awful things keep happening in Cranbury. Why are all the men apparently gray-suited zombies? Why do all the children—if you ever see them—behave like clones? And what has happened to Mig's brother, Chris? Could gentle, civilized Aunt Maria, with her talk and daily tea parties, possibly have anything to do with it?

Diana Wynne Jones once again has created a fantastic, magical world. Her brilliant storytelling and wonderful sense of humor totally involve the reader in the lives of a lovable young heroine and a villainess readers will love to hate.
