I've always been a big sci-fi fan, but my interest has had a strong resurgence since I really got serious about writing another book. The Instapundit has provided many useful recommendations. Now, I hope to crib my reading list from the Hugo Award winners and nominees.
I have yet to read any of the nominees from this year or last year, but I read three from 2006, including the winner, Spin, and found them not only to be enjoyable but exhilarating. This year's nominees are out. One of the nominees, John Scalzi, has a nice and in-depth post about the nominees and overlooked books.
