Currently making my way through the Ice Planet Barbarians series by Ruby Dixon and even though the first one feels like she read Clan of the Cave Bear and watched James Cameron's Avatar and thought "these need to combined and at least 20x hornier" I AM EATING IT UP.

I also LOVED The DaVinci Code and Angels and Demons by Dan Brown. I still own the beautiful illustrated versions of each and reading the story and looking at the art pieces and locations referenced is a fantastic experience.
