A Deadly Wandering tells the story of Reggie Shaw, a Utah college student whose Chevy Tahoe veered into another lane one night in 2006 and clipped a car carrying two rocket scientists, which then collided head-on with a truck, killing the two men. Shaw was texting a friend at the time of the accident. Richtel casts a wide net in the telling of this story, including a cast of characters that ranges from the scientists’ widows and children to lawmakers, prosecutors, neuroscientists and one tireless victim’s advocate.
