How might a small decision you make, an action you take, a phone call you initiate change your path? Impact other lives? Months after spying a bottle wedged into a fallen cottonwood snag in the Columbia River, Ernest pulls it from the river. The bottle's note connects Ernest, an old man living in a tiny Oregon town, to teenage Annie, provoking a mysterious and sudden friendship between Ernest's daughter Amelia with Sarah, the daughter of the most recent resident of the home Annie once occupied. The two middle-aged women's quest to learn more about Annie and her secret introduces readers to stories about family members through backstory, and introduces new characters, all connected through the finding of the bottle. Together, Amelia and Sarah explore their unfinished business with their mothers, intimate relationships, and regrets over life choices as they embark on their personal searches for something bigger in their very different lives.

AS ALEX PRUD’HOMME and his great-aunt Julia Child were completing their collaboration on her memoir, My Life in France, they began to talk about the French obsession with bottled water, which had finally spread to America. From this spark of interest, Prud’homme began what would become an ambitious quest to understand the evolving story of freshwater. What he found was shocking: as the climate warms and world population grows, demand for water has surged, but supplies of freshwater are static or dropping, and new threats to water quality appear every day. The Ripple Effect is Prud’homme’s vivid and engaging inquiry into the fate of freshwater in the twenty-first century. The questions he sought to answer were urgent: Will there be enough water to satisfy demand? What are the threats to its quality? What is the state of our water infrastructure—both the pipes that bring us freshwater and the levees that keep it out? How secure is our water supply from natural disasters and terrorist attacks? Can we create new sources for our water supply through scientific innovation? Is water a right like air or a commodity like oil—and who should control the tap? Will the wars of the twenty-first century be fought over water? Like Daniel Yergin’s classic The Prize: The Epic Quest for Oil, Money & Power, Prud’homme’s The Ripple Effect is a masterwork of investigation and dramatic narrative. With striking instincts for a revelatory story, Prud’homme introduces readers to an array of colorful, obsessive, brilliant—and sometimes shadowy—characters through whom these issues come alive. Prud’homme traversed the country, and he takes readers into the heart of the daily dramas that will determine the future of this essential resource—from the alleged murder of a water scientist in a New Jersey purification plant, to the epic confrontation between salmon fishermen and copper miners in Alaska, to the poisoning of Wisconsin wells, to the epidemic of intersex fish in the Chesapeake Bay, to the wars over fracking for natural gas. Michael Pollan has changed the way we think about the food we eat; Alex Prud’homme will change the way we think about the water we drink. Informative and provocative, The Ripple Effect is a major achievement.

An epic science fiction novel. A young woman (Beth) leads a science research team on a distant world at the same time as another team, protected by a large armed force, mine for precious ore. The science team genetically modify some members of one species, ape-like bipeds, to help provide labour. When the ruthless leader of the mining camp (Catanda) decides he will keep some of the ore for his personal gain, and he exterminates members of another mining group, the peaceful people of the science camp find themselves pitched in deadly conflict with Catanda and the armed forces. They seek refuge among the ape-people as a struggle begins for all their survival when Catanda threatens to exterminate them. They appear to have little hope of winning a conflict against a superior and technological armed force. A story of immortal love, ruthlessness, and the endless struggle of good against evil set in the jungle and desert of a young world. With links to videos, posters, and additional material on the internet to enrich the reader's experience. Authored by Mol Smith (Maurice Smith), a writer and creator of six feature films and numerous shorts for a small UK film production company: Onview Films; and a book which shares his unique style.
