The Goblin Emperor, by Katherine Addison.
The premise: in the Elflands, the Emperor and his three sons die in a tragic airship crash, leaving the only heir his reviled, half-blood son, Maia. Dubbed the Goblin Emperor, he must navigate the labrynthine politics of his new seat of power, the Imperial Court. Who can he trust? Who must he plot against? And who was behind the airship crash, which is eventually deemed foul play?
Just a great story so far. Maia is a wonderful, sensitive character, and the court really comes alive. You will want to root for the half-blood to succeed.
