You faithlessly leave behind the novel you are working on, pushing it aside rather abruptly as your creative flow kicks in with a rush of adrenaline that is reminiscent of first love, bringing with it exciting plot lines, memorable characters and story twists at a pace you can hardly keep up with - jotting down the first chapter; racing to the novels conclusion; working on chapter headings; character flaws and, and, and.. and slowly.. decisively you hit on a sub plot that's shocks you, but is both so believable and doable that maybe, just maybe it will make an interesting if not controversial read..
