The Goblin Emperor,

Fantasy novel by Sarah Monette under the pseudonym Katherine Addison.

A standalone novel in the fantastic world of Katherine Addison's award-winning The Goblin Emperor. When young half-goblin emperor Maia sought to learn who had killed his father and half-brothers in The Goblin Emperor, he turned to an obscure resident of his court, a Witness for The Dead named Thara Celehar. Now, far from the court, Thara Celehar lives in quasi-exile, neither courtier nor prelate, serving the common people of the city. He lives modestly, communicating with the dead as is his duty. But his decency and fundamental honesty will not permit him to live quietly. Celehar will follow the truth wherever it leads him no matter who may be implicated in murder, fraud, or ancient injustices.
