On the Plain of Snakes by Paul Theroux

Nogales is a border town caught between Mexico and the United States of America. A forty-foot steel fence runs through its centre, separating the prosperous US side from the impoverished Mexican side. It is a fascinating site of tension, now more than ever, as the town fills with hopeful border crossers and the deportees who have been caught and brought back. And it is here that Paul Theroux will begin his journey into the culturally rich but troubled heart of modern Mexico. Mexico is a country that has captured literary imaginations from D. H. Lawrence and Graham Greene to Aldous Huxley. Now Paul Theroux, master of travel writing, immerses himself, attending local language and culinary schools, driving through the country, getting under its skin.
