Merde Happens by Stephen Clarke
All Books are second hand
Paul West is in deep financial merde. His only way out of debt is to accept a decidedly dodgy job that involves him touring America in a Mini, while pretending to be typically British.
Also in the car is Paul's French girlfriend, Alexa, and his American poet friend, Jake, whose main aim in life is to sleep with a woman from every country in the world. Preferably in the back of Paul's Mini.
