This indispensable biography of a road profiles the 117 miles of Britain's most infamous motorway, from its controversial origins to its present-day status as backdrop to the lives and commutes of millions. Told with Ray Hamilton's trademark powers of observation and off-the-wall humour, it is an eye-opening account of the stuff you didn't know about the M25 – including the action, sightseeing or nature-loving fun you can have coming off at any junction – and a very different view of the stuff you did know.
