    Hawken, an environmentalist and author, has spent more than a decade researching organizations dedicated to restoring the environment and fostering social justice. From billion-dollar nonprofits to single-person causes, these organizations collectively comprise the largest movement on earth. This is a movement that has no name, leader, or location, but is in every city, town, and culture. It is organizing from the bottom up and is emerging as an extraordinary and creative expression of people’s needs worldwide. Blessed Unrest explores the diversity of this movement, its brilliant ideas, innovative strategies, and centuries-old history. The culmination of Hawken’s many years of leadership in these fields, it will inspire, surprise, and delight anyone who is worried about the direction the modern world is headed. Blessed Unrest is a description of humanity’s collective genius and the unstoppable movement to re-imagine our relationship to the environment and one another. Like Hawken’s previous books, Blessed Unrest will become a classic in its field— a touchstone for anyone concerned about our future.

    What we don’t see is the arduous, life-threatening challenges they face at every moment. Beaks, Bones, and Bird Songs guides the reader through the myriad, and often almost miraculous, things that birds do every day to merely stay alive. Like the goldfinch, which manages extreme weather changes by doubling the density of its plumage in winter. Or urban birds, which navigate traffic through a keen understanding of posted speed limits. In engaging and accessible prose, Roger Lederer shares how and why birds use their sensory abilities to see ultraviolet, find food without seeing it, fly thousands of miles without stopping, change their songs in noisy cities, navigate by smell, and much more.

    He was a city boy, unsure of what lay ahead. When he entered the forest, which would go on to become one of the last strongholds of wild tigers, it had a profound effect on him, changing his life forever.For the next forty years, he studied nearly 200 Ranthambhore tigers, spending every waking moment in close proximity to these magnificent animals. Of the various tigers he observed a handful became extra special, and it is these which come to glorious life in this book. They include Padmini, the Queen Mother, the first tiger the author got to know well; Genghis, the master predator, who invented a way of killing prey in water, the first time this had been observed anywhere in the world; Noon, one of his all-time favourites, who received her name because she was most active in the middle of the day; Broken Tooth, an exceptionally gentle male; Laxmi, a devoted mother, whose methods of raising her cubs revolutionized tiger studies; Machli, the most famous tigress in Ranthambhore, and several more.

    They don't even know about her ex-girlfriends or her fake IDs.But it's that fake ID that leads her to the hottest club in the city. While her friends tear up the dancefloor, however, Audrey meets the foil to her suppressed desires and curiosity.Dylan. The resident bad girl with an affinity for good girls like Audrey.What begins as a torrid fling soon transforms into something that opens Audrey's eyes to the life she's always wanted. The longer she's with Dylan, the more she realizes the sources of her suffocation. A toxic family. Airheaded friends. Caring for nothing but the trappings of wealth. "A bad girl is someone who refuses to accept the status quo." Dylan has dated her fair share of heiresses, but Audrey is the first one to make her believe in a chance at love.Yet it's not easy to give over to someone like Audrey. She represents everything Dylan has spent her whole life rejecting, for she knows all too well what it's like to be forced into the good girl role.And her past is constantly threatening to ruin everything she's built for herself since her darkest days. "Good girls don't go bad. They save themselves." The fatalistic love that haunts both Dylan and Audrey will last the summer. After that? Someone will have to give up the only life they've ever known.Easier said than done.Please note that this book contains examples of transphobia and growing up in an abusive cult.

    Created through a "student-tested, faculty-approved" review process with over 150 students and faculty, PSYCH 2 is an engaging and accessible solution to accommodate the diverse lifestyles of today's learners.

    Four little girls--Nicole, Amy, Charlotte, and Grace--are eleven years old and the very best of friends. They have sleepovers, picnics and ice-skating parties that exclude Binah, a beautiful girl whose seemingly perfect life makes them "green with envy." However, when a feisty, pumpernickel-loving fairy godmother takes them on a magical journey, they learn to their great surprise that Binah's life is not nearly as enviable as it had seemed. The English Roses is an inspiring story about the importance of compassion and the rewards of friendship.

    Socrates' last words were about it. Charles Darwin and Louis Pasteur made their scientific breakthroughs using it. Catholic popes, African shamans, Chinese philosophers, and Muslim mystics praised it. Throughout the history of civilization, humans have embraced it in every form imaginable—as a messenger of the gods, powerful sex symbol, gambling aid, emblem of resurrection, all-purpose medicine, handy research tool, inspiration for bravery, epitome of evil, and, of course, as the star of the world's most famous joke.In Why Did the Chicken Cross the World?, science writer Andrew Lawler takes us on an adventure from prehistory to the modern era with a fascinating account of the partnership between human and chicken (the most successful of all cross-species relationships). Beginning with the recent discovery in Montana that the chicken's unlikely ancestor is T. rex, this book builds on Lawler's popular Smithsonian cover article, "How the Chicken Conquered the World" to track the chicken from its original domestication in the jungles of Southeast Asia some 10,000 years ago to postwar America, where it became the most engineered of animals, to the uncertain future of what is now humanity's single most important source of protein.In a masterful combination of historical sleuthing and journalistic exploration on four continents, Lawler reframes the way we feel and think about our most important animal partne—and, by extension, all domesticated animals, and even nature itself.Lawler's narrative reveals the secrets behind the chicken's transformation from a shy jungle bird into an animal of astonishing versatility, capable of serving our species' changing needs. For no other siren has called humans to rise, shine, and prosper quite like the rooster's cry: "cock-a-doodle-doo!"

    

    As miraculous a feat of nature as the snowflakes has been, have we ever been truly able to appreciate this infinitesimal wonder in all its crystalline glory? Art of the Snowflake, as much a work of art as a testament to science, reveals how one of the snowflake's most inspired photographers came to such intimate knowledge of his craft and its fleeting focus. Beautiful pictures illustrate Kenneth Libbrecht's story of the microphotography of snow crystals, from the pioneering work of Wilson Bentley in the 1890s right up to Ken's own innovations in our age of digital images. A breathtaking look at the works of art that melt in an instant, this is a book to flip through and savor, season after season.
