The final book about the heroes of Trainspotting. Mark Renton finally achieves success. A regular at fancy resorts, he now makes serious money as a DJ, but the constant travel, waiting rooms, soulless hotel rooms and broken relationships leave him feeling dissatisfied with his life. One day he accidentally runs into Frank Begbie, from whom he has been hiding for many years after a terrible betrayal that entailed a debt. But psychopath Frank seems to have found himself, becoming a celebrated artist and, to Mark's amazement, has no interest in revenge. Dead Man and Potato, with their own plans, are intrigued by the return of old friends, but once they become part of the harsh world of organ trafficking, everything goes wrong inclined Reeling from crisis to crisis, the four boys circle each other, driven by personal stories and addictions, confused, angry - so desperate that even Hibs' Scottish Cup win doesn't help. One of these four will not live to see the end of the book. So which of them bears the mark of death?
