Richard of Bordeaux and Henry Bolingbroke were first cousins, born just three months apart. Their lives were from the beginning entwined. When they were still children, Richard was crowned King Richard II with Henry at his side- a ten-year-old lord in the service of his ten-year-old king. Yet they soon grew up to be opposites- Richard was the white hart, a thin-skinned narcissist, and Henry the eagle, a chivalric hero, a leader who inspired loyalty where Richard inspired only fear. Increasingly threatened by his charismatic cousin, Richard became consumed by the need for total power, and the stage was set for a final confrontation. This is a story about a nation brought to the brink of catastrophe - and two men whose lives were played out in parallel, to devastating effect.
