We tried loads of photographic approaches for this cover before arriving at this. I created this illustration as a last-minute entry to the Cover Meeting, and amazingly it ended up being the finished jacket. Here's the finished cover, plus a close-up of the illustration.
"I say there is no darkness but ignorance." William Shakespeare. Any intelligence we may have come upon is only by chance, our lives are ruled by chance, so we cannot judge harshly those lives that have not had the good chance to see beyond the ignorance that surrounds much of life.
