In 1461 Edward earl of March, an able, handsome, and charming eighteen-year old, usurped the English throne from his feeble Lancastrian predecessor Henry VI. Ten years on, following outbreaks of civil conflict that culminated in him losing, then regaining the crown, he had finally secured his kingdom. The years that followed witnessed a period of rule that has been described as a golden age: a time of peace and economic and industrial expansion, which saw the establishment of a style of monarchy that the Tudors would later develop. Yet, argues A. J. Pollard, Edward, who was drawn to a life of sexual and epicurean excess, was a man of limited vision, his reign remaining to the very end the narrow rule of a victorious faction in civil war. Ultimately, his failure was dynastic: barely two months after his death in April 1483, the throne was usurped by Edward's youngest brother, Richard III.

No English king has so divided opinion, both during his reign and in the centuries since, more than Richard III. He was loathed in his own time for the never-confirmed murder of his young nephews, the Princes in the Tower, and died fighting his own subjects on the battlefield. This is the vision of Richard we have inherited from Shakespeare. Equally, he inspired great loyalty in his followers. In this enlightening, even-handed study, Rosemary Horrox builds a complex picture of a king who by any standard failed as a monarch. He was killed after only two years on the throne, without an heir, and brought such a decisive end to the House of York that Henry Tudor was able to seize the throne, despite his extremely tenuous claim. Whether Richard was undone by his own fierce ambitions, or by the legacy of a Yorkist dynasty which was already profoundly dysfunctional, the end result was the same: Richard III destroyed the very dynasty that he had spent his life so passionately defending.

'He seems to have laboured under an almost child-like misapprehension about the size of his world. Had greatness not been thrust upon him, he might have lived a life of great harmlessness.' The reign of Edward II was a succession of disasters. Unkingly, inept in war, and in thrall to favourites, he preferred digging ditches and rowing boats to the tedium of government. His infatuation with a young Gascon nobleman, Piers Gaveston, alienated even the most natural supporters of the crown. Hoping to lay the ghost of his soldierly father, Edward I, he invaded Scotland and suffered catastrophic defeat at the Battle of Bannockburn. After twenty ruinous years, betrayed and abandoned by most of his nobles and by his wife and her lover, Edward was imprisoned in Berkeley Castle and murdered - the first English king since the Norman Conquest to be deposed.

Edward VI, the only son of Henry VIII, became king at the age of nine and died wholly unexpectedly at the age of fifteen. All around him loomed powerful men who hoped to use the child to further their own ends, but who were also playing a long game - assuming that Edward would long outlive them and become as commanding a figure as his father had been. Stephen Alford's wonderful book gives full play to the murky, sinister nature of Edward's reign, but is also a poignant account of a boy learning to rule, learning to enjoy his growing power and to come out of the shadows of the great aristocrats around him. England's last child monarch, Edward would have led his country in a quite different direction to the catastrophic one caused by his death.

'After my death,' George V said of his eldest son and heir, 'the boy will ruin himself within twelve months.' The forecast proved uncannily accurate. Edward VIII came to the throne in January 1936, provoked a constitutional crisis by his determination to marry the American divorcée Wallis Simpson, and abdicated in December. He was never crowned king. In choosing the woman he loved over his royal birthright, Edward shook the monarchy to its foundations. Given the new title 'Duke of Windsor' and essentially sent into exile, he remained a visible skeleton in the royal cupboard until his death in 1972 and he haunts the house of Windsor to this day. Drawing on unpublished material, notably correspondence with his most loyal (though much tried) supporter Winston Churchill, Piers Brendon's superb biography traces Edward's tumultuous public and private life from bright young prince to troubled sovereign, from wartime colonial governor to sad but glittering expatriate. With pace and panache, it cuts through the myths that still surround this most controversial of modern British monarchs.
