Do you have an under-noticed author that you think we should all know about?
I completely concur with Parajunkee, Maria V. Snyder is amazing. I absolutely love her Study Series.
Some other authors I would love to see get more attention are Stacia Kane whose dark urban fantasy the Downside series was incredible, C.L. Wilson and her Tairen soul series that is both romantic and a wonderful fantasy adventure, and Elizabeth Haydon who created such an amazing world in her Symphony of Ages epic fantasy series.
