Well known for his histories of Norman Sicily, Venice, the Byzantine Empire and the Mediterranean, John Julius Norwich has now turned his attention to the oldest continuing institution in the world, tracing the papal line down the centuries from St Peter himself – traditionally (though by no means historically) the first pope – to the present Benedict XVI.Of the 280-odd holders of the supreme office, some have unques­tionably been saints; others have wallowed in unspeakable iniquity.

Once in a generation, a historian will redefine his field, producing a book that demands to be read or heard - a product of electrifying scholarship conveyed with commanding skill. Diarmaid MacCulloch's Christianity is such a book. Breathtaking in ambition, it ranges back to the origins of the Hebrew Bible and covers the world, following the three main strands of the Christian faith.

The First World War is one of history’s greatest tragedies. In this remarkable and intimate account, author G. J. Meyer draws on exhaustive research to bring to life the story of how the Great War reduced Europe’s mightiest empires to rubble, killed 20 million people, and cracked the foundations of the world we live in today. World War I is unique in the number of questions about it that remain unsettled. After more than 90 years, scholars remain divided on these questions, and it seems likely that they always will.

The name Borgia is synonymous with the corruption, nepotism and greed that were rife in Renaissance Italy. Notorious for seizing power, wealth, land and titles through bribery, marriage and murder, the dynasty’s dramatic rise from its Spanish roots to its occupation of the highest position in Renaissance society forms a gripping tale. Erudite, witty and always insightful, Hibbert removes the layers of myth around the Borgia family and creates a portrait alive with a superb sense of character and place.

The Borgia family have become a byword for evil. Corruption, incest, ruthless megalomania, avarice, and vicious cruelty - all have been associated with their name. And yet, paradoxically, this family lived when the Renaissance was coming into its full flowering in Italy. Examples of infamy flourished alongside some of the finest art produced in western history.
