A favorite is Ken Follett. I am totally absorbed in his trilogy of Fall of Giants, Winter of the World and the soon-to-be-released third book. The series starts in the 20s and runs through both world wars. I have been watching Downton Abbey and the Upstairs Downstairs series, so it all falls in line. Pillars of the Earth is an all-time favorite as well. I studied architecture and design in college and read this inspirational book then.
