The Voyage of the Minotaur is a fantasy novel set in a Victorian/Steampunk world.
Cafe Carlo is a restaurant in the Great Plaza of Brech City. As a 6-8 year old, Senta works there cleaning the wrought iron fence and sweeping the walk. Carlo, the fat proprietor seems to be a stuffy, stingy fellow from her point of view, but others remark that he is kind and loves children. The line cook at Cafe Carl is Gyula Kearn, who lost one arm in a factory. He makes a return in the fifth book of the series.
