Novelist Mary Kubica's fifth thriller, When The Lights Go Out, launches this week. The best-selling author told Spine that each of her books starts with the flicker of an idea, which she fans from several angles to see if anything alights. "A book often begins with a small, subconscious spark of inspiration that's then molded in a very conscious way to see if the spark has legs," she said. "For When The Lights Go Out, that first spark was the twist itself, which was exciting because it's never happened for me this way. Usually I have no idea how my books will end, but only a beginning!"
