Drawn to the natural world, for years she worked as a ranger in National Parks, at times living in her run-down car (which lacked a reverse gear), on abandoned construction sites, or camping on a piece of land in Montana she bought from a colleague. She managed to put herself through college and then graduate school, eventually earning a Ph.D. in biology.Yet she never felt at home with people, and though she worked at various universities and taught field classes in the National Parks, she built a house on a remote plot of land in Montana and, except when teaching, spoke to no one. One day, she realized that the fox who had been appearing at her house was coming by every day at 4:15. He became a regular visitor, who eventually sat near her as she read to him from The Little Prince or Dr. Seuss. Her scientific training had taught her not to anthropomorphize animals, but as she grew to know him, his personality revealed itself—and he became her friend. But friends cannot always save each other from the uncontained forces of nature.Though this is a story of survival, it is also a poignant and dramatic tale of living in the wilderness and coping with inevitable loss. This uplifting fable-like true story about the friendship of a woman and a wild fox not only reveals the power of friendship and our interconnectedness with the natural world but is an original, imaginative, and beautiful work that introduces a stunning new voice.

    The consequences of losing beavers were profound: streams eroded, wetlands dried up, and species from salmon to swans lost vital habitat. Today, a growing coalition of “Beaver Believers”―including scientists, ranchers, and passionate citizens―recognizes that ecosystems with beavers are far healthier, for humans and non-humans alike, than those without them. From the Nevada deserts to the Scottish highlands, Believers are now hard at work restoring these industrious rodents to their former haunts. Eager is a powerful story about one of the world’s most influential species, how North America was colonized, how our landscapes have changed over the centuries, and how beavers can help us fight drought, flooding, wildfire, extinction, and the ravages of climate change. Ultimately, it’s about how we can learn to coexist, harmoniously and even beneficially, with our fellow travelers on this planet.

    Smith. But, thanks to the determination of a powerful senator, he would soon find himself at the agency’s helm. A Birkenstocks-wearing physics PhD, Jaczko was unlike any chairman the agency had ever seen: he was driven by a passion for technology and a concern for public safety, with no ties to the industry and no agenda other than to ensure that his agency made the world a safer place. And so Jaczko witnessed what outsiders like him were never meant to see—an agency overpowered by the industry it was meant to regulate and a political system determined to keep it that way. After an emergency trip to Japan to help oversee the frantic response to the horrifying nuclear disaster at Fukushima in 2011, and witnessing the American nuclear industry’s refusal to make the changes he considered necessary to prevent an equally catastrophic event from occurring here, Jaczko started saying aloud what no one else had dared. Confessions of a Rogue Nuclear Regulator is a wake-up call to the dangers of lobbying, the importance of governmental regulation, and the failures of congressional oversight. But it is also a classic tale of an idealist on a mission whose misadventures in Washington are astounding, absurd, and sometimes even funny—and Jaczko tells the story with humor, self-deprecation, and, yes, occasional bursts of outrage. Above all, Confessions of a Rogue Nuclear Regulator is a tale of confronting the truth about one of the most pressing public safety and environmental issues of our time: nuclear power will never be safe.

    In Don't Look Behind You, Allison recounts adventures few would live to tell.

       The grizzly is one of North America’s last large predators. Their range is diminished, but they’re spreading into the West again, where once they were king. The challenge: humans rule the roost now, and most are wary, at best, as grizzlies approach.     In searing detail, award‑winning writer, Montana rancher, and conservationist Bryce Andrews tells us about one such grizzly. Millie was a typical mother: strong, cunning, fiercely protective of her cubs. But raising those cubs was hard. The mountains were changing, as the climate warmed and people crowded the valleys. There were obvious dangers, like poachers, and subtle ones, like the corn field that drew her into human territory, and sure trouble.     That trouble is where Bryce’s story intersects with Millie’s. He shares both in Down from the Mountain, showing how this singular drama is a piece of a much larger one in the West: an entangled, bloody collision between people protecting a life they’ve known for generations, and the people fighting to preserve one of America’s wildest landscapes.

    And no delay causes more parental anxiety than late talking, which is associated in many parents' minds with such serious conditions as autism and severe intellectual disability. In fact, as children's speech expert Stephen Camarata points out in this enlightening book, children are late in beginning to talk for a wide variety of reasons. For some children, late talking may be a symptom of other, more serious, problems; for many others, however, it may simply be a stage with no long-term complications.Camarata describes in accessible language what science knows about the characteristics and causes of late talking. He explains that late talking is only one of a constellation of autism symptoms. Although all autistic children are late talkers, not all late-talking children are autistic.Camarata draws on more than twenty-five years of professional experience diagnosing and treating late talkers--and on his personal experience of being a late talker himself and having a late-talking son. He provides information that will help parents navigate the maze of doctors, speech therapists, early childhood services, and special education; and he describes the effect that late talking may have on children's post-talking learning styles.

    Jameson's account of one intrepid man's efforts to find the lost treasures of North America and beyond. Jameson and his partners piece together centuries-old histories through documents, maps, and stories passed down from one generation to the next, facing life-threatening danger time and again. These riveting stories, told with humor and candor, are a portal to another time, and are a testament to the spirited independence of risk-takers, a few of whom still exist in what we think of as the modern age.

    In exquisite prose, John Lewis-Stempel records the passage of the seasons from cowslips in spring to the hay-cutting of summer and grazing in autumn, and includes the biographies of the animals that inhabit the grass and the soil beneath: the badger clan, the fox family, the rabbit warren, the skylark brood and the curlew pair, among others. Their births, lives, and deaths are stories that thread through the book from first page to last.In Meadowland Lewis-Stempel does for meadows what Roger Deakin did for woodland and rivers in his bestselling books Wildwood and Waterlog.
