A Feast for Crows by George R. R. Martin
It's the 4th book in the best fiction series I've ever read (A Song of Fire and Ice).
That is a very good fantasy series. I'm waiting for Feast of Crows to come out in paperback.

You might also enjoy the series Malazan Book of the Fallen by Canadian writer (and anthroplogist) Steven Eriksen. Darker, funnier and more complex that Martin. Five books already published in a planned 10 book series:

In SF I'm also awaiting the sequel to Hamilton's "Pandora's Star", called "Judas Unleashed", and the sequel to Simmon's "Ilium" titled "Olympos".
