As Constant Reader may recall, I like invented-world fantasies with lots of worldbuilding and history and complicated politics and cultural issues and yummy things like that. The Goblin Emperor is exactly this, and being so well-written and with such fascinating characters, I was immediately drawn into it and devoured it with delight. Sarah Monette, writing as Katherine Addison, has created something wonderful here.
It's a fish out of water court intrigue - protagonist Maia is the unloved and unregarded fourth son of the Emperor of the Elflands, the child of a political match between his father and a princess of Barizhan - the land of the goblins. Both mother and son were banished from court, and after his mother's early death, Maia is raised in a remote town by his resentful, out of favour kinsman who abuses him. Maia's life seems destined to be lonely and unpleasant, until a terrible accident - later found to be sabotage - takes the life of his father and three older brothers, leaving him the heir to the throne of Elfland.
Maia comes to the throne totally unprepared, with no knowledge of politics, the nation's concerns, the intricacies of court life, the duties of an emperor, the bureaucracy and endless paperwork that keeps an empire running. What he does have is a natural honesty, a desire to serve and do the best for his people, and a likable nature that eventually wins him a few key allies amidst a court that views him with disdain as a half-blood savage who does not deserve to rule.
It's the essential decency of the main character that sells the novel from the first page. The reader wants Maia to learn how to thread his way through the complexities of politics, the mechanics of government and the court intrigues, to come into his own and heal a land where divisions along lines of race, class and gender have resulted in a host of abuses, great and small, institutional and personal.
It's a complex and wonderful story, with much to enjoy, and much to think about.
