'It isn't often that one reads a book and is convinced that it's an instant classic, but I'm sure that LONDON ORBITAL will be read 50 years from now. This account of his walk around the M25 is on one level a journey into the heart of darkness, that terrain of golf courses, retail parks and industrial estates which is Blair's Britain. It's a fascinating snapshot of who we are, lit by Sinclair's vivid prose, and on another level a warning that the mythological England of village greens and cycling aunts has been buried under the rush of a million radial tyres' J. G. Ballard, Observer
