I write romance. A lot of it. Everything from contemporary to paranormal to romantic suspense. I get bored easily so I move around a lot.
Same with reading...but I read almost everything-romance, urban fantasy, science fiction, thrillers, just about everything. Except non-fiction. Generally have enough reality in my life.
I'm published with several different houses, have several different series. My most popular series seem to be my Hunters and my Grimm for my paranormal and the Rafferty brothers for my romantic suspense.
