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's something strange about the pupils of Rotwood - everyone's dressed as though it's Halloween and the school's motto is 'Because We Scare'. Is ten-year-old Maud Montague monstrous enough for Rotwood? The first book in the frighteningly fantastic Monstrous Maud series.
