Now that Game of Thrones is a huge success, and in the wake of the tremendous success of Lord of the Rings and the Hobbit movies, I want someone to finally take note of Katherine Kurtz' Deryni Chronicles. I loved those books and read everyone of them, including the offshoot novels about Camber of Culdi. Here's a site where you can see cover art and read synopses of the books which have all the intrigue, magic, and complicated family relationships you could ever want.
I'm also a fan of Kurtz' lesser-known novel Lammas Night, which is set during WW2 and deftly mixes magic and the mundane in a story that feels real, even though it's about a coven of witches who band together to save their country from a German invasion. Read the book and imagine Prince Harry as the novel's heroic prince.
