I suppose all sorts-- it depends on my mood. I do enjoy history and historical novels. But I also enjoy stories involving chivalry, knights, and heroic tales. I don't mind philosophy, either. I take great enjoyment from having a physical copy of a book in my hands and finding somewhere comfortable to read. I'm willing to explore most genres, so long as they are tasteful.
