What pushed Blunt, Burgess, Cairncross, Maclean and Philby into Soviet hands? With access to recently released papers and other neglected documents, this sharp analysis of the intelligence world examines how and why these men and others betrayed their country and what this cost Britain and its allies. Enemies Within is a new history of the influence of Moscow on Britain told through the stories of those who chose to spy for the Soviet Union. It also challenges entrenched assumptions about abused trust, corruption and Establishment cover-ups that began with the Cambridge Five and the disappearance of Guy Burgess and Donald Maclean on the night boat to Saint-Malo in 1951. In a book that is as intellectually thrilling as it is entertaining and illuminating, Richard Davenport-Hines traces the bonds between individuals, networks and organisations over generations to offer a study of character, both individual and institutional. At its core lie the operative traits of boarding schools, the universities of Oxford and Cambridge, the Intelligence Division, Foreign Office, MI5, MI6 and Moscow Centre. Davenport-Hines tells many stories of espionage, counter-espionage and treachery. With its vast cope, ambition and scholarship, Enemies Within charts how the undermining of authority, the rejection of expertise and the suspicion of educational advantages began, and how these have transformed the social and political temper of modern Britain.

By picking up this book, you are probably either considering keeping exotic pets, or you already have an interest in them. Not only are many of these creatures extremely beautiful to look at but they are also much simpler to look after than some of the more traditional pet mammals and birds with whom we choose to share our lives.Among the most popular pet amphibians, tree frogs are remarkably easy to look after and many species are suitable for handling by keepers.

The breakthrough novel from one of Britain's most brilliant critics. 'The Mulberry Empire' is a seemingly straightforward historical novel that recounts an episode in the Great Game in central Asia -- the courtship, betrayal and invasion of Afghanistan in the 1830s by the emissaries of Her Majesty's Empire, which is followed by the bloody and summary expulsion of the Brits from Kabul following an Afghani insurrection (shades of the Soviet Union's final imperial fling in the very same country in the 1980s). The novel has at its heart the encounter between West and East as embodied in the likeable, complex relationship between Alexander Burnes, leader of the initial British expeditionary party, and the wily, cultured Afghani ruler, the Amir Dost Mohammed Khan.

Ian Newton is an ornithologist and applied scientist, and a leading expert on bird ecology and biogeography, specialising in finches, waterfowl and birds of prey, especially the sparrowhawk. He graduated from Bristol University and gained his doctorate at Oxford. He joined the NERC in 1967, initially studying population ecology of geese and finches, followed by the impact of pesticides on birds of prey. He has written three previous New Naturalist volumes, Finches (1972), Bird Migration (2010) and Bird Populations (2013).

I recall the New Forest in childhood and explored it in the 1950s. It has been my home and I have been involved in its affairs since 1960 when almost by accident I found myself working in the Nature Conservancy (since 1974 the NCC). The Forest has not been my only professional concern or research interest since then, but it has been of constant and absorbing interest. The absorption grows with time – partly because over long time spans, it becomes possible to measure and witness changes which illuminate the relationships between soils, vegetation, animals and management in ways which no short-term study can achieve; and partly because time increases rather than diminishes the degree of spiritual renewal and intellectual wonder to be derived from the familiar woods and heaths.

Operation Marriage… Prince Quinton Carlow’s life was turned upside down the day his divorce was filed and his military papers were executed. Seven years later, the embittered soldier returns, only to walk straight back into his ex-wife! But when Quinn discovers he’s still married to the one woman who could claim his heart, he realises he must tackle the past for the future he wants…the future Anais wants too. But can he convince his Cinderella bride to fight for their love?

A tense and layered true-crime story about an all-American soldier boy turned bank robber Alex Blum was a clean-cut all-American kid with one unshakeable goal in life: to serve his country in the military. He was accepted into the elite Rangers regiment, but on the first day of his leave before deployment to Iraq, Alex got into his car with two fellow soldiers and two strangers, drove to a local bank in Tacoma, and committed armed robbery. The Blum family was devastated and mystified. How could he have done such a thing? Alex’s attorney presented a defence based on the theory that trainee Rangers are indoctrinated on a level akin to the brainwashing in an extreme religious cult, and Alex insisted that he had believed the robbery was just another exercise in the famously daunting Ranger program. But Luke Elliot Sommer, the charismatic soldier behind the robbery, maintained that Alex knew exactly what he was doing, and had, in fact, planned it all with him. Who was lying? What had happened to Alex during those gruelling months of training? How accountable was he?

Imagine a sisterhood – across all creeds and cultures. An unspoken agreement that we, as women, will support and encourage one another. That we will remember we don't know what struggles each of us may be facing elsewhere in our lives and so we will assume that each of us is doing our best… So begins WE: an inspiring, empowering and provocative manifesto for change. Change which we can all effect, one woman at a time. Change which provides a crucial and timely antidote to the 'have-it-all' Superwoman culture and instead focusses on what will make each and every one of us happier and more free. Change which provides an answer to the nagging sense of 'is that it?' that almost all of us can succumb to when we wake in the dead of night. Written by actress Gillian Anderson and journalist Jennifer Nadel – two friends who for the last decade have stumbled along together, learning, failing, crying, laughing and trying again – WE is a not a theoretical treatise but instead a rallying cry to create a life that has greater meaning and purpose. Combining tools which are practical, psychological and spiritual, it is both a process and a vision for a more fulfilling way of living. And a truly inspiring vision of a happier, more emotionally rewarding future we can all create together…
