Recently I read the book Northlight by Deborah Ross. It's categorized as science fiction and fantasy, but it's light on the science fiction side. The world created by the author is fantastical, but also very similar to that on Earth. It's more realistic than it's categorization implies. As the author puts it, it's really "a tale of healing and adventure and some very cool horses" (Northlight Introduction).
