Gordath Wood [EPUB ebook] 

Something strange is happening in Gordath Wood, the old woods surrounding a training stable called Hunter’s Chase. The police think Lynn Romano and Kate Mossland have been murdered, but what actually occurred is much stranger. They’ve gone through a hole between worlds, into a medieval society at war. In a world that doesn’t ordinarily have use for women, the danger is great — good thing Lynn and Kate aren’t your ordinary women.
