The Nsefu lion pride would be perfect, with six new cubs, strong males to defend them, and the best territory on Luangwe River in Zambia. But, they've got teenagers! Seven gawky hopeless adolescent lions are learning how to hunt, and forgetting their manners. Then, one night they injure one of the cubs, and have a disastrous buffalo hunt. One teenager, a yearling, is killed, two injured, and three lost. The lost three brothers have wandered into the next-door territory, and discover their neighbours. What they find turns their family upside down, and when the two prides come together, the lion family is fractured by betrayal and rage.
