If you're into historical fiction there are a couple of authors and series I'd like to recommend.
Conn Iggulden
He has two epic series:
One about Caesar and his rise to power.
The other is about Ghengis Khan
Bernard Cornwell
One of my favorite series I've ever read is the
Saxon series - it's all about the Danish viking raids and occupation of England.
The other is the
Grail Quest series - this one is about the search for the grail at the time of the 100years war.
