There are many authors I like, and quite a few who's blogs I follow. One of my favourites is Maria V. Snyder. She writes mostly fantasy, and she's got a new book that just came out - the third installment of a trilogy. This trilogy is a spin-off of a previous trilogy, so there are 6 books to explore the fantasy world she's created.
You can check out an interview with her here: http://bittenbybooks.com/?p=30706
