I don't read Stephen King either - at least not his scary stuff. I like to sleep at night, you know.
Since I write romance, I tend to read heavily in that genre. Pretty much everything except erotica. Not my bag.
I also like books outside of romance. Authors like Orson Scott Card, Mercedes Lackey, Catherine Asaro, Marion Zimmer Bradley - fantasy & sci-fi are great! I recently finished Anthony Bourdain's Kitchen Confidential and it was a very interesting read. I love to cook, so anything chef-related is usually a green light for me.
