Thief

A bit needs to be explained. First, Kitty's real name is Kalasin. (Stole it from Tamora Pierce because I thought it was pretty) Second, no one knows that Kitty is Kalasin, the Queen of Thieves. Third, the Court of Thieves is a following of the Thief that she doesn't acknowledge. She refuses to accept them because she works alone. Third, I'm not sure if Smyrna is a real place but Emeraldis isn't. This takes place in an alternate universe from our own. There is magic, dragons, and an easily identifiable enemy.
