Chinese Ed is dreaming. Michael Kearney is being haunted by fractal geometry. And something is waking up in the Kefahuchi Tract, far out in space.
This makes the book sound far more pretentious than it is. Light is three separated stories and it is not until the last few pages that you realise they are not separate at all. The future is solid and logical while the present is ethereal and bizarre; the small cast (almost like a play) is comprised of colourful and well-considered characters. Highly recommended. You'll never see a horse's skull in the same way again.
