If you like books set in different times I recommend the Kingsbridge series by Ken Follett, starts with Pillars of the Earth which is a really long book at was made into a mini-series on Starz in the US. He writes a lot of books set in different times and the Trilogy Series is quite good but many of his others, while not actually series are all great period pieces too. A Dangerous Fortune, A Place Called Freedom, The Key to Rebecca and multiple others are all set in some period in history. He does tend to have some weird sex scenes in his books so if that is an issue you should avoid them but it's never terribly graphic or the focus of the stories.

It's really, really good and will suck you in pretty quickly. Might want to start with one of his shorter books to see if you like his style though, I've read just about everything he's written starting with Eye of the Needle a long time ago.
