Over the last half billion years, there have been five major mass extinctions, when the diversity of life on Earth suddenly and dramatically contracted. Scientists are currently monitoring the sixth extinction, predicted to be the most devastating since the asteroid impact that wiped out the dinosaurs. This time around the cataclysm is us. In this book the author tells us why and how human beings have altered life on the planet in a way no species has before. She provides a moving account of the disappearances of various species occurring all around us and traces the evolution of extinction as concept, from its first articulation by Georges Cuvier in revolutionary Paris up to Lyell and Darwin, and through the present day. The sixth extinction is likely to be mankind's most lasting legacy, compelling us to rethink the fundamental question of what it means to be human. -- Publisher description.

"Following the catastrophes of the twenty-first century--the pandemics, the environmental disaster, the end of oil, the ensuing chaos--people are doing whatever they can to get by and pursuing a simpler and sometimes happier existence. In little Union Grove, the townspeople are preparing for Christmas. Without the consumerist shopping frenzy that dogged the holidays of the previous age, the season has become a time to focus on family and loved ones. It is a stormy Christmas Eve when Robert Earle's son Daniel arrives back from his two years of sojourning throughout what is left of the United States. He collapses from exhaustion and illness, but as he recovers tells the story of the break-up of the nation into three uneasy independent regions and his journey into the dark heart of the New Foxfire Republic centered in Tennessee and led by the female evangelical despot, Loving Morrow. In the background, Union Grove has been shocked by the Christmas Eve double murder by a young mother, in the throes of illness, of her husband and infant son. Town magistrate Stephen Bullock is in a hanging mood"--

In a post-oil America with no electricity, no Internet, dwindling resources, and little civic order, the residents of the small town of Union Grove, New York, must deal with roving bandits and a sinister cult that threatens to shatter the hamlet's stability.

In Union Grove, early spring is a challenging season, known as the "six weeks want," a time when fresh food is scarce and the winter stores are dwindling. The town is struggling in particular this year as the Hudson River trade route to Albany has been halted by the local plantation tycoon Stephen Bullock, who has deemed it too resource-intensive and is now striving for self-sufficiency. Meanwhile, after returning from his travels around what is left of the United States, Daniel Earle is intent on resurrecting a newspaper for the community, and finds an interesting story to cover when representatives of a group of anti-establishment, hyper-liberals known as the Berkshire People's Republic arrive in the town.
