"Deserves a spot next to Fast Food Nation and To Kill a Mockingbird in America’s high school curriculums. To say it may save lives is self-evident.” —New York Times Book Review (Editor's Choice) NEW YORK TIMES BESTSELLER • A BEST BOOK OF THE YEAR: San Francisco Chronicle, Chrisitian Science Monitor, Kirkus, Winnipeg Free Press One of the decade's most original and masterfully reported books, A Deadly Wandering by Pulitzer Prize–winning New York Times journalist Matt Richtel interweaves the cutting-edge science of attention with the tensely plotted story of a mysterious car accident and its aftermath to answer some of the defining questions of our time: What is technology doing to us? Can our minds keep up with the pace of change? How can we find balance? On the last day of summer, an ordinary Utah college student named Reggie Shaw fatally struck two rocket scientists while texting and driving along a majestic stretch of highway bordering the Rocky Mountains. A Deadly Wandering follows Reggie from the moment of the tragedy, through the police investigation, the state's groundbreaking prosecution, and ultimately, Reggie's wrenching admission of responsibility. Richtel parallels Reggie's journey with leading-edge scientific findings on the impact technology has on our brains, showing how these devices play to our deepest social instincts. A propulsive read filled with surprising scientific detail, riveting narrative tension, and rare emotional depth, A Deadly Wandering is a book that can change—and save—lives.
