The Amur River is almost unknown. Yet it is the 10th longest river in the world, rising in the Mongolian mountains and flowing through Siberia to the Pacific. For 1,100 miles, it forms the tense border between Russia and China. Haunted by the memory of land-grabs and unequal treaties, this is the most densely fortified frontier on Earth. In his 80th year, Colin Thubron takes a dramatic journey from the Amur's secret source to its giant mouth, covering almost 3,000 miles.

Author, filmmaker and conservationist Roger Deakin first came to fame with his best-selling book Waterlog, which brought wild swimming into the mainstream and pioneered the 'new nature writing' genre. Published posthumously, his second travelogue, Wildwood, and collected journals, Notes from Walnut Tree Farm, were also hailed as classics.

After moving from London to a new home in Yorkshire, and about to become a father for the first time, Rob Cowen finds himself in unfamiliar territory. Disoriented, hemmed in by winter and yearning for open space, he ventures out to a nearby edge-land: a pylon-slung tangle of wood, hedge, field, meadow and river that lies unclaimed and overlooked on the outskirts of town. Digging deeper into this lost landscape, he begins to uncover its many layers and lives - beast, bird, insect, plant and people - in kaleidoscopic detail.

On June 8th, 1924, George Mallory and 'Sandy' Irvine set out to stand on the roof of the world, where no one had stood before. They were last seen 800 feet shy of Everest's summit. A century later, we still don't know whether they achieved their goal, decades before Sir Edmund Hillary and Tensing Norgay did, in 1953. Irvine carried a Kodak camera with him to record their attempt, but it, along with his body, had never been found. Did Mallory and Irvine reach the summit and take a photograph before they fell to their deaths?

Edith Widder grew up determined to become a marine biologist. But after complications from a surgery during college caused her to go temporarily blind, she became fascinated by light as well as the power of optimism. Below the Edge of Darkness explores the depths of the planet's oceans as Widder seeks to understand bioluminescence, one of the most important and widely used forms of communication in nature.

As a small boy, Bill François was frightened of deep water. Until a chance encounter with the elusive sardine set him on course for a life in marine science: a mission to better understand, and preserve, the underwater world, to find his place in that ecosystem and learn how to converse harmoniously with the ocean. In a series of exquisitely rendered vignettes of marine life, François invites us on a whistle-stop global tour to reveal the mysteries of the sea, beginning with the simple eloquence of the sardine.

For the last 50 years, the trees of the boreal forest have been moving north. The Treeline takes us along this critical frontier of our warming planet from Norway to Siberia, Alaska to Greenland, to meet the scientists, residents, and trees confronting huge geological changes.

When Kinari Webb first traveled to Indonesian Borneo at 21 to study orangutans, she was both awestruck by the beauty of her surroundings and heartbroken by the rain forest destruction she witnessed. As she got to know the local communities, she realized that their need to pay for expensive health care led directly to the rampant logging, which in turn imperiled their health and safety even further. Webb realized her true calling was at the intersection of medicine and conservation.

As a graduate student exploring the rain forests of Australia, Meg Lowman realized that she couldn’t monitor her beloved leaves using any of the usual methods. So she put together a climbing kit: she sewed a harness from an old seat belt, gathered hundreds of feet of rope, and found a tool belt for her pencils and rulers. Up she went, into the trees. Forty years later, Lowman remains one of the world’s foremost arbornauts, known as the “real-life Lorax.”

Part memoir, part homage to wilderness, Shearwater traces the author’s 50-year obsession with one of nature’s supreme travellers. In the finest tradition of nature writing, Roger Morgan-Grenville, author of Liquid Gold - described by Mary Colwell (Curlew Moon) as ‘a book that ignites joy and warmth’ - unpicks the science behind its incredible journey; and into the story of a year in the shearwater’s life, he threads the inspirational influence of his Hebridean grandmother who instilled in him a love of wild places and wild animals.

The ice sheets and glaciers that cover one-tenth of Earth's land surface are today in grave peril. High in the Alps, Andes, and Himalaya, once-indomitable glaciers are retreating, even dying. Meanwhile, in Antarctica, thinning glaciers may be unlocking vast quantities of methane stored for millions of years beneath the ice. In Ice Rivers, renowned glaciologist Jemma Wadham offers a searing personal account of glaciers and the rapidly unfolding crisis that they - and we - face.

Coral reefs are a microcosm of our planet: extraordinarily diverse, deeply interconnected, and full of wonders. When they’re thriving, these fairy gardens hidden beneath the ocean’s surface burst with color and life. They sustain bountiful ecosystems and protect vulnerable coasts. Corals themselves are evolutionary marvels that build elaborate limestone formations from their collective skeletons, broker symbiotic relationships with algae, and manufacture their own fluorescent sunblock.

Dylan Tomine takes us to the far reaches of the planet in search of fish and adventure, with keen insight, a strong stomach, and plenty of laughs along the way. Closer to home, he wades deeper into his beloved steelhead rivers of the Pacific Northwest and the politics of saving them. Tomine celebrates the joy - and pain - of exploration, fatherhood, and the comforts of home waters from a vantage point well off the beaten path. Headwaters traces the evolution of a lifelong angler’s priorities from fishing to the survival of the fish themselves.

Some of the only truly feral cattle in the world wander a long-abandoned island off the northernmost tip of Scotland. A variety of wildlife not seen in many lifetimes has rebounded on the irradiated grounds of Chernobyl. A lush forest supports thousands of species that are extinct or endangered everywhere else on earth in the Korean peninsula's narrow DMZ.

From conservation to protecting endangered species to sustainable living, A Christian's Guide to Planet Earth offers a faith-based framework for viewing our responsibility to the natural world as well as practical, biblical ways we can care for the magnificent creation around us. Drawing on science and Scripture, this hope-filled and listener-friendly guide helps us navigate questions about caring for and respecting God's world.

The ice sheets and glaciers that currently cover one-tenth of the planet's land surface are today in grave peril. Locked up within them is a vast proportion of Earth's freshwater - but the ice is fast melting as our climate warms at an accelerating rate. High up in the Alps, Andes and Himalaya, once-indomitable glaciers are retreating, even dying; meanwhile, in Antarctica, thinning glaciers are releasing meltwater to sensitive marine foodwebs and may be unlocking vast quantities of methane stored for millions of years in the deep beneath the ice.

In The Sea Inside, Philip Hoare sets out to rediscover the sea, its islands, birds and beasts. He begins on the south coast where he grew up, a place of almost monastic escape. From there he travels to the other side of the world - the Azores, Sri Lanka, New Zealand - in search of encounters with animals and people. Navigating between human and natural history, he asks what these stories mean for us now.

Nowhere on our planet is devoid of life. Plants and animals thrive or survive within every extreme of climate and habitat that it offers. Single species, and often whole communities, adapt to make the most of ice cap and tundra, forest and plain, desert, ocean and volcano. These adaptations can be truly extraordinary. In Living Planet, David Attenborough’s searching eye, unfailing curiosity and infectious enthusiasm explain and illuminate the intricate lives of the these colonies.

Trees clean air and water; hoverflies and bees pollinate our crops; the kingfisher inspired the construction of high-speed trains. In Tapestries of Life, best-selling author Anne Sverdrup-Thygeson explains how closely we are all connected with the natural world, highlighting our indelible link with nature’s finely knit system and our everyday lives.
