I love this book. I always read it before I go to London. For a fan of the London Underground it is a must-read. Andy has to travel to every station the day before his wedding after a drunken bet with a 'friend' who is in posession of his passport, honeymoon tickets and credit cards, all of which have been hidden in various stations across the network. Andy meets a tramp called Brian along the way who you can't help but end up liking. And you can't help but root for Andy along the way and hope it all comes good in the end. The best way to read this book is in 24 hours as that's the amount of time (roughly) the book is set. It's a funny but touching book.
