Richard II (1377-99) came to the throne as a child, following the long, domineering, martial reign of his grandfather Edward III. He suffered from the disastrous combination of a most exalted sense of his own power and an inability to impress that power on those closest to the throne. Neither trusted nor feared, Richard battled with a whole series of failures and emergencies before finally succumbing to a coup, imprisonment and murder. Laura Ashe's brilliant account of his reign emphasizes the strange gap between Richard's personal incapacity and the amazing cultural legacy of his reign - from the Wilton Diptych to Sir Gawain and the Green Knight, Piers Plowman and The Canterbury Tales.

A major new title in the Penguin Monarchs series In his fascinating new book in the Penguin Monarchs series, Richard Abels examines the long and troubled reign of Aethelred II the 'Unraed', the 'Ill-Advised'. It is characteristic of Aethelred's reign that its greatest surviving work of literature, the poem The Battle of Maldon, should be a record of heroic defeat. Perhaps no ruler could have stemmed the encroachment of wave upon wave of Viking raiders, but Aethelred will always be associated with that failure. Richard Abels is Professor Emeritus at the United States Naval Academy. He is the author of Alfred the Great: War, Kingship and Culture in Anglo-Saxon England and Lordship and Military Obligation in Anglo-Saxon England. He is a Fellow of the Royal Historical Society.

'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 Drawing on unpublished material, notably correspondence with his most loyal (though much tried) supporter Winston Churchill, Piers Brendon's superb biography traces Edward's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.

Henry II (1154-89) through a series of astonishing dynastic coups became the ruler of an enormous European empire. One of the most dynamic, restless and clever men ever to rule England, he was brought down both by his catastrophic relationship with his archbishop Thomas Becket and his debilitating arguments with his sons, most importantly the future Richard I and King John. His empire may have ultimately collapsed, but in Richard Barber's vivid and sympathetic account the reader can see why Henry II left such a compelling impression on his contemporaries.

'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.

From the celebrated historian and author of Europe: A History, a new life of George II George II, King of Great Britain and Ireland and Elector of Hanover, came to Britain for the first time when he was thirty-one. He had a terrible relationship with his father, George I, which was later paralleled by his relationship to his own son. He was short-tempered and uncultivated, but in his twenty-three-year reign he presided over a great flourishing in his adoptive country - economic, military and cultural - all described with characteristic wit and elegance by Norman Davies. (George II so admired the Hallelujah chorus in Handel's Messiah that he stood while it was being performed - as modern audiences still do.) Much of his attention remained in Hanover and on continental politics, as a result of which he was the last British monarch to lead his troops into battle, at Dettingen in 1744.

'James was a king tragically trapped by principle. Yet was it wise to attempt to change the national religion?' The short reign of James II is generally seen as one of the most catastrophic in British history, ending in his exile after he unsuccessfully tried to convert England to Catholicism, a crisis that would haunt the monarchy for generations. Ultimately, David Womersley's biography shows, James was a man whose blindness to subtlety and political reality brought about his ruinous downfall.
