Crowfood's Daughter

I would like to add in "The Wierwoods" by Thomas Burnett Swann? It is about the Etruscans who have a centuries long pact with the people of a wooded place called the Weirwoods. The people of these woods are called the Weir ones and there are some who are much like the CotF with slitted gold cat eyes and also webbed feet that make a squish sound when they walk. Anyway there is a father who breaks this pact and steals a weir-one for his daughter as a slave.
