In the tradition of Silent Spring and The Sixth Extinction, an urgent, meticulously researched, and groundbreaking book about the ways in which chemicals in the modern environment are changing—and endangering—human sexuality and fertility on the grandest scale, from renowned epidemiologist Shanna Swan. In 2017, author Shanna Swan and her team of researchers completed a major study. They found that over the past four decades, sperm levels among men in Western countries have dropped by more than 50 percent. They came to this conclusion after examining 185 studies involving close to 45,000 healthy men. The result sent shockwaves around the globe—but the story didn’t end there. It turns out our sexual development is changing in broader ways, for both men and women and even other species, and that the modern world is on pace to become an infertile one. How and why could this happen? What is hijacking our fertility and our health? Count Down unpacks these questions, revealing what Swan and other researchers have learned about how both lifestyle and chemical exposures are affecting our fertility, sexual development—potentially including the increase in gender fluidity—and general health as a species. Engagingly explaining the science and repercussions of these worldwide threats and providing simple and practical guidelines for effectively avoiding chemical goods (from water bottles to shaving cream) both as individuals and societies, Count Down is at once an urgent wake-up call, an illuminating read, and a vital tool for the protection of our future.

How do you make one month last a lifetime? Karina Ahmed has a plan. Keep her head down, get through high school without a fuss, and follow her parents’ rules—even if it means sacrificing her dreams. When her parents go abroad to Bangladesh for four weeks, Karina expects some peace and quiet. Instead, one simple lie unravels everything. Karina is my girlfriend. Tutoring the school’s resident bad boy was already crossing a line. Pretending to date him? Out of the question. But Ace Clyde does everything right—he brings her coffee in the mornings, impresses her friends without trying, and even promises to buy her a dozen books (a week) if she goes along with his fake-dating facade.

T-minus twenty-eight days until everything returns to normal—but what if Karina no longer wants it to? "I. Love. This.

When Deborah Gold and her husband signed up to foster parent in their rural mountain community, they did not foresee that it would lead to a roller-coaster fifteen years of involvement with a traumatized yet resilient birth family. They fell in love with Michael (a toddler when he came to them), yet they had to reckon with the knowledge that he could leave their lives at any time. In Counting Down, Gold tells the story of forging a family within a confounding system. We meet social workers, a birth mother with the courage to give her children the childhood she never had herself, and a father parenting from prison. We also encounter members of a remarkable fellowship of Appalachian foster parents—gay, straight, right, left, evangelical, and atheist—united by love, loss, and quality hand-me-downs. Gold’s memoir is one of the few books to deliver a foster parent’s perspective (and, through Michael’s own poetry and essays, that of a former foster child). In it, she shakes up common assumptions and offers a powerfully frank and hopeful look at an experience often portrayed as bleak.
