Monstrous Maud: Big Fright

There's something spooky about Maud's new school, in the first book in this fun and scary new series
 
When Maud's pet rat, Quentin, escapes in the middle of science class, it's the very last straw. Maud is transferred from Primrose Towers to Rotwood Middle School—to the delight of her teacher, classmates and her perfect twin, Milly—but what is in store at Rotwood? There is something strange about the pupils of Rotwood. Everyone is dressed as though it's Halloween, and the school's motto is "Because We Scare." Is 10-year-old Maud Montague monstrous enough for Rotwood?
