The end of the 12th century, the heyday of the Angevin Empire, created by Henry II. The empire includes England and a good half of France. Enemies tremble before Henry, but there is no peace in his family - the sons constantly rebel against the will of their father and quarrel among themselves. Which of them will inherit the crown: the frivolous Hal, the warlike but hot-tempered Richard, the crafty Geoffrey or the childish John? From the conquered lands of Ireland, the Irish youth O Cahoin, whom the victors nicknamed Rufus for his red hair, arrives in England as a hostage. Here he will meet one of the most legendary warriors in history, Richard Plantagenet, nicknamed the Lionheart, to become his squire, and then a knight, and take part in dozens of battles with him. For the first time in Russian!
