An account of a cross-country adventure chasing butterflies: “Armchair travelers who love a good yarn will find Pyle’s exuberance catching.” —Seattle Times
Part road-trip tale, part travelogue of lost and found landscapes, all good-natured natural history, Mariposa Road tracks Bob Pyle’s journey across the United States as he races against the calendar in his search for as many of the eight hundred American butterflies as he can find. Like Pyle’s classic Chasing Monarchs, Mariposa Road recounts his adventures, high and low, in tracking down butterflies in his own low-tech, individual way.
Accompanied by Marsha, his cottonwood-limb butterfly net; Powdermilk, his 1982 Honda Civic with 345,000 miles on the odometer; and the small Leitz binoculars he has carried for more than thirty years, Bob ventured out in a series of remarkable trips from his Northwest home. From the California coastline in company with overwintering monarchs to the Far Northern tundra in pursuit of mysterious sulphurs and arctics; from the zebras and daggerwings of the Everglades to the leafwings, bluewings, and border rarities of the lower Rio Grande; from Graceland to ranchland and Kauai to Key West, these intimate encounters with the land, its people, and its fading fauna are wholly original. At turns whimsical, witty, informative, and inspirational, Mariposa Road is an extraordinary journey of discovery that leads the reader ever farther into butterfly country and deeper into the heart of the naturalist.
“What Roger Tory Peterson was for birds, Bob Pyle is for butterflies . . . From the dusty heat of Texas and the tropical lushness of Hawaii to the legendary outhouse of the Midnight Sun in the Alaskan Arctic, Pyle is a traveling companion who never grows dull.” —Scott Weidensaul, author of Of a Feather

Adolescence is a time of great ferment and change. When messages abound that tell a young person they are not enough, they tend to concentrate their energies on being prettier, smarter, or more popular. What does this leave out? Kelly and Tom Shelstad offer wilderness programs and other activities that have proven to be of help to young people and their families as they traverse the treacherous waters from childhood to adulthood in a way that supports self-esteem and self-knowledge. Each wilderness experience includes a built-in “purposeful challenge” of alone time. This is a time without the “normal” distractions of our addiction to electronic input, friends, Facebook, Twitter, TV, or car. It is a time when the participant can start to feel bored. Tom describes this time: “When we start feeling bored we try to do something to distract ourselves, to not feel it. But, if we are willing to sit in those feelings, there’s much wisdom, personal understanding, and empowerment that arises from that level of self inquiry.” This conversation highlights the benefits of how the exploration of wilderness can shift the need for outside validation. It helps teens to be more confident in their own skin, recognizing their authentic selves from the inside out. They will have met the challenge and recognize themselves for who they actually are instead of who they put themselves up to be on their Facebook page, Instagram, or Twitter.

A groundbreaking study on the lives of senior mammals and birds—from the aging of alphas to the role of grandmothers—by the author of Animal Friendships.
How do young and old social animals view each other? Are aged animals perceived by others as weaker? Or wiser? What is the relationship between age and power among social animals?
Taking a cue from Frans de Waal’s seminal work examining the lives of chimpanzees, Anne Innis Dagg in this pioneering study probes the lives of older mammals and birds. Synthesizing the available scientific research and anecdotal evidence, she explores how aging affects the lives and behavior of animals ranging from elk to elephants and gulls to gorillas, examining such topics as longevity; how others in a group view senior members in regard to leadership, wisdom, and teaching; mating success; interactions with mates and offspring; how aging affects dominance; changes in aggressive behavior and adaptability; and death and dying.
At once instructive and compelling, this theme-spanning book reveals the complex nature of maturity in scores of social species and shows that animal behavior often displays the same diversity we find in ourselves.
“Dagg’s book should be a corrective to us all; species that lose or ignore the contributions of their older members do so at their peril.” —Literary Review of Canada
“Humans and chimps, it turns out, value age in sexual partners very differently. In our species youth is prized, but among chimps the reverse is the case.” —The New York Review of Books
In this critically acclaimed international bestseller, Petros Papachristos, a mathematical prodigy, has devoted much of his life trying to prove one of the greatest mathematical challenges of all time: Goldbach's Conjecture, the deceptively simple claim that every even number greater than two is the sum of two primes. His feverish and singular pursuit of this goal has come to define his life. Now an old man, he is looked on with suspicion and shame by his family-until his ambitious young nephew intervenes.
Seeking to understand his uncle's mysterious mind, the narrator of this novel unravels his story, a dramatic tale set against a tableau of brilliant historical figures-among them G. H. Hardy, the self-taught Indian genius Srinivasa Ramanujan, and a young Kurt Gödel. Meanwhile, as Petros recounts his own life's work, a bond is formed between uncle and nephew, pulling each one deeper into mathematical obsession, and risking both of their sanity.
