Mabel lives with her parents in the Mermaid Hotel, where she keeps an eye on all the guests, particularly her friend, the endlessly fascinating Madame Badobedah. Madame Badobedah, who considers herself part of a long tradition of daring women such as Amelia Earhart and Zora Neale Hurston, has pirouetted through pyramids, swum with mermaids, and helped a triceratops with a toothache.
