... the Lymond Chronicles and the House of Niccolo series are set in the Renaissance. She uses a lot of dialect in the first, so it's a tough read. Lindsey Davis combines the genres of historical fiction and the detective series in her books about Marcus Didius Falco, set during Vespasian's reign. My favorite for the Matter of Britain is The Pendragon by Catherine Christian, which sets Arthur during the period of the breakup of the Roman Empire in Britain. I also like Neal Stephenson's Baroque Cycle, which along with Necronomicon combine history and information theory.
I like to read novels written in certain eras to get a feel for the times, even though the books are not "historical fiction" per se. The novel really got going in the 18th century (a lot of them were bodice-rippers of a sort), although there are a few examples that antedate that period.
R.F. Delderfield wrote a slew of historical novels, many of them adapted for the big or little screen. A lot of the themes of his work revolve around early 20th century social history subjects, especially adapting to society after the Great War and the increased de-ruralization of England. Then, of course, we have Nobel laureate John Galsworthy with The Forsyte Saga, which in a way combines that idea of historical and period writing.
One could go on. When it comes to historical fiction, there is no end to the number of books written.
