Smashwords Interview

What do your fans mean to you?
I write for myself. I publish stories I think other people might enjoy. I call my readers 'reading buddies' because I hope they will be with me for years. I never want to disappoint them.
If this is part of series, how did you come up with the idea for the series?
Dark Thoughts is the first story in the Refuge series. We first meet Kralj, the hero of this first story, in one of my other series. He was so fascinating I knew I had to write his story. Dark Thoughts is a standalone and assumes you haven't read any of my other stories.
