Whether labeled as such or not, I think every book I've ever written has been, more or less, a romantic suspense. I have always put tremendous effort into making each book a page turner: The harder it is for the reader to put it down, the better I've done my job.
To me, romance and suspense go hand in hand. What's more suspenseful than wondering how two wonderful people can manage to get together in spite of the world going crazy around them?
I enjoy heroines who grow and come into their own during the course of a story.
