Visitors to luxury London hotels may want to pick up a copy of Walk the Lines: The London Underground, Overground, before hitting the capital for a unique view of the city.
Author Mark Mason presents an account of London life by walking the entire length of the London Underground – overground – passing every station along the way.
On his journey he highlights the sights, sounds and characteristic features of each spot on his tour of "the greatest city on earth".
Mr Mason introduced his book by saying: "One city, 11 tubes lines, 269 stations, 403 miles, 912,384 footsteps, countless overheard conversations, more London facts than you could shake an A to Z at and one very battered pair of trainers."
As a lifelong fan of the city, Mr Mason says his extreme journey has helped him to come to understand the sprawling metropolis but insists that it never ceases to surprise him.
"This engaging book puts its best foot forward with fascinating detail about both the Underground and its part in London's history," commented the Independent's book reviewer Jonathan Sale.
"Mason's 400-mile trek – a 'horizontal Everest' – turns him into a human version of the Google street map."
On his journey through London, Mr Mason is joined by colourful characters, such as a City planner, a Tube expert, a trainee taxi driver and the Kray twins' biographer.
Visitors to the city interested in learning more about the unique transport network can stop in on the London Transport museum in Covent Garden.
