Danny Wallace is about to turn thirty and his life has become a cliche. Recently married and living in a smart new area of town, he's swapped pints down the pub for lattes and brunch. For the first time in his life, he's feeling, well ... grown-up. But something's not right. Something's missing. Until he finds an old address book containing just twelve names. His best mates as a kid. Where are they now? Whoare they now? And how are theycoping with being grown-up too? And so begins a journey from A-Z, tracking down and meeting his old gang. He travels from Berlin to Tokyo, from Sydney to LA. He even goes to Loughborough. He meets Fijian chiefs. German rappers. Some ninjas. And a carvery manager who's managed to solve time travel. But how will they respond to a man they haven't seen in twenty years, turning up and asking if they're coming out to play? Part-comedy, part-travelogue, part-memoir, Friends Like Theseis the story of what can happen when you track down your past, and of where the friendships you thought you'd outgrown can take you today...
