The Queen's Thief series (1996-2010) by Megan Whalen Turner
These four YA fantasy novels, set in classical Greece, follow a man named Eugenides ("Gen"), who claims that he can steal anything. In each book, we learn more about his life, but from a variety of perspectives, including those of the king and queen of Attolia. See Turner's website for summaries of each book and links to reviews.
