Katherine Addison continues her series about the Witness for the Dead, Thara Celehar, in The Tomb of Dragons. As the story opens, Celehar has lost his ability to hear the dead and is a bit lost. Circumstances get him kidnapped, and his ability returns as he encounters the unrestful spirit of a murdered dragon who wants justice for herself and for the other 191 dragons murdered by a company that wanted their mines. Celehar, of course, sets off to find that justice, navigating a complex social and political world to do so.
