The Hard Part of Writing?

I've been playing around with fiction for a few months now, since starting this blog. Deep down I know that I can do it. I've been writing for a very long time, and I've been told over and over that people can identify with me. I don't talk down to my readers and they appreciate it. That feedback has been the same for over twenty years, but it pertains to my non-fiction writing. I love that people can relate to me, and like me. So, what's the problem? I'm still not sure I can write the type of fiction I love. Why can't I write a story about afternoon tea in the garden, or a mother and daughter growing an herb garden together? Some days I feel like I'm two people. There is the down to earth, gardener, cook and mom who loves tea sets, roses, herbs and country living. I like her. But then there is this other person inside me. The one who owns the Buffy the Vampire Slayer DVDs. The one who's read every Terry Goodkind book, and loves to see good kick evils butt all the over the place. The one who loves those sexy vampire warriors J.R. Ward writes about, and the one who wants to hang out with paranormal romance writers and readers.

I'm wondering if there is a way to join my two halves so I can write something with the style my non-fiction readers love, but use the ideas in my head that involve kicking butt and taking no prisoners. Is that even possible?

What do you think?
