'The greatest nature writer in the world ... He is also the greatest travel writer ... [an] astounding new memoir' Sunday Times

'Horizon is magnificent; a contemporary epic' Robert Macfarlane, author of Underland

From the author of the classic Arctic Dreams comes a vivid recollection of his travels around the world and the encounters that have shaped an extraordinary life.

Taking us nearly from pole to pole - from modern megacities to some of the earth's most remote regions - and across decades of lived experience, Barry Lopez gives us his most far-ranging yet personal work to date, in a book that describes his travels to six regions of the world: from Western Oregon to the High Arctic; from the Galapagos to the Kenyan desert; from Botany Bay in Australia to finally, unforgettably, the ice shelves of Antarctica.

Lopez also probes the long history of humanity's quests and explorations, including the prehistoric peoples who trekked across Skraeling Island in northern Canada, the colonialists who plundered Central Africa, an enlightenment-era Englishman who sailed the Pacific, a Native American emissary who found his way into isolationist Japan, and today's ecotourists in the tropics.

Throughout his journeys - to some of the hottest, coldest, and most desolate places on the globe - and via friendships with scientists, archaeologists, artists and local residents, Lopez searches for meaning and purpose in a broken world.

Horizon is a revelatory, epic work that voices concern but also hope - a book that makes you see the world differently, and that is the crowning achievement by one of America's great voices.
