But the world that she encountered in the field was dramatically different than anything she could have imagined. In this honest and irreverent memoir, she introduces readers to the reality of the life of an aid worker. We watch as she helps to resettle refugees in Rwanda, manages a 24,000-person camp in Darfur, and helps a former child soldier in Sierra Leone get rid of a tattoo that was carved into his skin by a rebel group. But we also see the alcoholic parties and fleeting romances, the burnouts and cyncism, the plans and priorities that constantly shift and change. Tracing her personal journey from idealistic and naïve newcomer to hardened cynic to hopeful but critical realist, Alexander transports readers to some of the most troubled locations and shows us not only the impossible challenges, but also the moments of hope and recovery.

    From her small-town home in Ontario, it seemed as if Marco Polo, Magellan and their like had long ago mapped the whole earth. So she vowed to become a scientist and go to Mars. To pass the time before she could launch into outer space, Kate set off by bicycle down a short section of the fabled Silk Road with her childhood friend Mel Yule, then settled down to study at Oxford and MIT. Eventually the truth dawned on her: an explorer, in any day and age, is by definition the kind of person who refuses to live between the lines. And Harris had soared most fully out of bounds right here on Earth, travelling a bygone trading route on her bicycle. So she quit the laboratory and hit the Silk Road again with Mel, this time determined to bike it from the beginning to end. Like Rebecca Solnit and Pico Iyer before her, Kate Harris offers a travel narrative at once exuberant and meditative, wry and rapturous. Weaving adventure and deep reflection with the history of science and exploration, Lands of Lost Borders explores the nature of limits and the wildness of a world that, like the self and like the stars, can never be fully mapped.

    A Time of Gifts is the first volume in a trilogy recounting the trip, and takes the reader with him as far as Hungary. It is a book of compelling glimpses - not only of the events which were curdling Europe at that time, but also of its resplendent domes and monasteries, its great rivers, the sun on the Bavarian snow, the storks and frogs, the hospitable burgomasters who welcomed him, and that world's grandeurs and courtesies. His powers of recollection have astonishing sweep and verve, and the scope is majestic. First published to enormous acclaim, it confirmed Fermor's reputation as the greatest living travel writer, and has, together with its sequel Between the Woods and the Water (the third volume is famously yet to be published), been a perennial seller for 25 years.

    For millennia it has been worshipped as a god; for centuries used as a tool of imperial expansion; today it is the cement of Pakistans fractious union. Five thousand years ago, a string of sophisticated cities grew and traded on its banks. In the ruins of these elaborate metropolises, Sanskrit-speaking nomads explored the river, extolling its virtues in Indias most ancient text, the Rig-Veda. During the past two thousand years a series of invaders Alexander the Great, Afghan Sultans, the British Raj made conquering the Indus valley their quixotic mission. For the people of the river, meanwhile, the Indus valley became a nodal point on the Silk Road, a centre of Sufi pilgrimage and the birthplace of Sikhism. Empires of the Indus follows the river upstream and back in time, taking the reader on a voyage through two thousand miles of geography and more than five millennia of history redolent with contemporary importance.
