The Custard Protocol

All alone in Singapore, proper Miss Primrose Tunstell must steal helium to save her airship, the Spotted Custard, in a scheme involving a lovesick werecat and a fake fish tail. When she uncovers rumors of a new kind of vampire, Prim and the Custard crew embark on a mission to Peru. There, they encounter airship pirates and strange atmospheric phenomena, and are mistaken for representatives of the Spanish Inquisition. Forced into extreme subterfuge (and some rather ridiculous outfits) Prim must also answer three of life's most challenging questions.

Percival Tunstell loves that his sister and her best friend are building themselves a family of misfits aboard their airship, the Spotted Custard. Of course, he'd never admit that he belongs among them. He's always been on the outside - dispassionate, aloof, and hatless. But accidental spies, a trip to Japan, and one smart and beautiful doctor may have him renegotiating his whole philosophy on life.
