The other reviews here left me a little puzzled, perhaps the readers found Sinclair a tad intimidating? I don't say this to be unkind, as at times, I too had to put the book down to take some respite from the barrage of information, images and references. This is more than just a piece of travel writing, it is the nexus of an almost overwhelming number of intertextual as well as geographic explorations. Iain Sinclair walked, not just through the physical locations he describes, but also through time, history and the sheer abstract. His wanderings as a modern day flaneur are inciteful, educated and hugely original. The story of a hike around the M25 really shouldn't be interesting, but Sinclair makes it so. He opens our eyes to the political and historical reality of the gradually increasing sprawl of London, as well as its psychological effects on modern life. I read this and then graduated to the even more intimidating 'Landor's Tower'. I'd recommend both highly, but unless you're widely read, you may have a little trouble keeping up with Sinclair's train of thought. He doesn't insult his readers, he assumes a high level of intelligence. A breath of fresh air in these times of trashy faddish novels and celebrity autobiographies...
