All of Laurell K. Hamilton's books are very good, but you don't find out that the two male vampires, Jean Claude and Asher, are as much into each other as they are into Anita until the last book, CERULEAN SINS. I highly recommend all of Hamilton's books.
The next Anita Blake book, INCUBUS DREAMS should be out in Oct. 2004. Her books are mostly hetro but the stories are great, and they are getting more gay as they go along. Bloody Bones has no gay parts, but it is a good story about a group of vampires and an out of control faerie!!
