Anything done well that sweeps you up with it.
I love the classics. Probably "Breakfast at Tiffany's" or "My Fair Lady" are at the top of my list at the moment.
Terry Pratchett, Terry Goodkind, Wilbur Smith, JK Rowling, Sara Douglass, David Eddings, Conn Iggulden, Katherine Kerr, C.S. Forester and George MacDonald Fraser are all well stocked on my book shelves. Oh, and some Dennis Wheatley.
