Nin had never liked Wednesdays; but this one took the biscuit. On this Wednesday she woke up to find that it was raining buckets and that her brother had ceased to exist. Ninevah realises she is the only person to remember Toby because whoever took him is about to make her disappear too. Enter Skerridge the Bogeyman; who steals kids for Mr. Strood. With his spindle; he draws all memories of Nin out of her mother's head. Nin escapes to the Drift; the world that her new friend Jonas and Mr. Strood inhabit. But the Drift is filled with the fabulous and the dreadful; tombfolk; mudmen; and the spirits of the seven sorcerers who once ruled the land. What is the secret of the Seven Sorcerers; and will Nin and Toby escape their fate at the House of Strood?
