The only book to fully chart the devastating opioid crisis in America: An unforgettable portrait of the families and first responders on the front lines, from a New York Times bestselling author and journalist who has lived through it. In this masterful work, Beth Macy takes us into the epicenter of America's twenty-plus year struggle with opioid addiction. From distressed small communities in Central Appalachia to wealthy suburbs; from disparate cities to once-idyllic farm towns; it's a heartbreaking trajectory that illustrates how this national crisis has persisted for so long and become so firmly entrenched. Beginning with a single dealer who lands in a small Virginia town and sets about turning high school football stars into heroin overdose statistics, Macy endeavors to answer a grieving mother's question-why her only son died-and comes away with a harrowing story of greed and need. From the introduction of OxyContin in 1996, Macy parses how America embraced a medical culture where overtreatment with painkillers became the norm. In some of the same distressed communities featured in her bestselling book Factory Man, the unemployed use painkillers both to numb the pain of joblessness and pay their bills, while privileged teens trade pills in cul-de-sacs, and even high school standouts fall prey to prostitution, jail, and death. Through unsparing, yet deeply human portraits of the families and first responders struggling to ameliorate this epidemic, each facet of the crisis comes into focus. In these politically fragmented times, Beth Macy shows, astonishingly, that the only thing that unites Americans across geographic and class lines is opioid drug abuse. But in a country unable to provide basic healthcare for all, Macy still finds reason to hope-and signs of the spirit and tenacity necessary in those facing addiction to build a better future for themselves and their families. "Everyone should read Beth Macy's story of the American opioid epidemic" -- Professor Anne C Case, Professor Emeritus at Princeton University and Sir Angus Deaton, winner of the Nobel Prize in Economics

When the people of Flint, Michigan, turned on their faucets in April 2014, the water pouring out was poisoned with lead and other toxins. Through a series of disastrous decisions, the state government had switched the city’s water supply to a source that corroded Flint’s aging lead pipes. Complaints about the foul-smelling water were dismissed: the residents of Flint, mostly poor and African American, were not seen as credible, even in matters of their own lives. It took eighteen months of activism by city residents and a band of dogged outsiders to force the state to admit that the water was poisonous. By that time, twelve people had died and Flint’s children had suffered irreparable harm. The long battle for accountability and a humane response to this man-made disaster has only just begun. In the first full account of this American tragedy, The Poisoned City recounts the gripping story of Flint’s poisoned water through the people who caused it, suffered from it, and exposed it. It is a chronicle of one town, but could also be about any American city, all made precarious by the neglect of infrastructure and the erosion of democratic decision making. Places like Flint are set up to fail—and for the people who live and work in them, the consequences can be fatal.
