I would say Katherine Addison's books - The Goblin Emperor and The Cemeteries of Amalo series have the feeling of deep history even if events of the books themselves are not exactly epic - you do constantly get references to the political and social changes in the past, unification of Elflands and the building of a city-sized palace that took three generations, suppression of a particular religious movement (a splinter faction of which still survives and even has been incorporated in the power structure of the kingdom, but people are polite enough not to mention it out loud), old-time civil wars in Elflands and the recent wars abroad, even a classic story where soldiers in a besieged city beyond any hope of relief killed their women and children and them killed themselves.
