There are four books by Megan Whalen turner that I've been reading (again). They are: The Thief, The Queen of Attolia, the King of Attolia, and A Conspiracy of Kings. You can find out more about them here. I've really enjoyed reading them. The characters between books change a little, but there are reoccurring characters, the main one being Eugenides. I read the first of these books in elementary or middle school, then re-read it and the next three a few years ago, and am re-reading them again. Have you read them? What do you think about them?
