I just found out that the fourth book in Megan Whalen Turner's Queen's Thief series is due out in 2010. Hurray!
The other books in the series are:
The Newberry Award winning The Thief
Book two, The Queen of Attolia
Book three, The King of Attolia
These are extremely clever, extremely entertaining books by one smart author. If you haven't read any of them, I would suggest you pick pick them up an read. Ms. Turner isn't the type of author to chug out one book after another. She takes her time and rewards her readers with clever gems to relish.
Oh, that I could be that clever.....
