London Orbital is Iain Sinclair's voyage of discovery into the unloved outskirts of the city.

Encircling London like a noose, the M25 is a road to nowhere, but when Iain Sinclair sets out to walk this asphalt loop - keeping within the 'acoustic footprints' - he is determined to find out where the journey will lead him. Stumbling upon converted asylums, industrial and retail parks, ring-fenced government institutions and lost villages, Sinclair discovers a Britain of the fringes, a landscape consumed by developers. London Orbital charts this extraordinary trek and round trip of the soul, revealing the country as you've never seen it before.

'A journey into the heart of darkness and a fascinating snapshot of who we are, lit by Sinclair's vivid prose. I'm sure it will be read fifty years from now'J. G. Ballard, Observer
