**A timeless story celebrating friendship and imagination, from an exciting new voice in children's literature.*Mabel lives with her parents in the Mermaid Hotel, by the sea. Mabel likes to keep an eye on the comings and goings of all the guests. Then one day a particularly in-ter-est-ing * old lady comes to stay. There is something very suspicious about her, with her growly voice and her heavy trunks and her beady-eyed tortoise. And why does no one know her REAL name? There can only be one answer, Mabel decides ... this guest is a SUPERVILLAIN.

But even supervillains have a soft side, and as an unlikely friendship grows between the pair, their fantastical exploits take them well beyond the corridors of their seaside home.
