Book and magazine writer, science fan and saucy speaker, Mary Roach brings humor and a bottomless pit of back-stories to Pierce County READS. Ariel Van Cleave, KNKX’s “Morning Edition” producer, will interview Mary Roach. How did she get into this line of work—and why are we so fascinated with everything that’s gross? Afterward, Roach will autograph books. Bring your own or purchase at the event.
