I'm a history buff (and your 300th upvoter today!). I like reading about the rise and fall of empires, brave leaders and all that they go through, as well as science fiction and anything dystopian. There's an amazing world out there brought to life in the mind of a good author.
I like history too! I also usually read stuff like Dean Koontz, but have gotten a little tired of it for now so trying some different things. Yes, a good author can help spark a good imagination.
