T Kingfisher, Summer in Orcus. A rather inventive take on the classic fantasy quest, but with plenty of innovation and it starts with Baba Yaga. It is not a comedy, but there are moments of humour. I particularly like it, that having started with Baba Yaga's mobile house on giant hens legs, that there is a passing mention later on of herds of wild houses out on the plain, and house hunters going after them.... Handled with a light touch.
