Diesel bookstore presents Matt Richtel, a novelist, cartoonist, and Pulitzer Prize-winning reporter for the New York Times, to discuss and sign his new thriller, Devil’s Plaything. The book is about a journalist, Nat Idl, who is nearly gunned down in Golden Gate Park. He quickly learns it was no random attack. Suddenly, in pursuit of the truth, he’s running for his life through the shadows of Silicon Valley, a human lab animal caught in a deadly maze of neurotechnology and institutional paranoia. And his survival rests entirely in the hands of his eighty-five-year-old grandmother, Lane, who’s suffering from dementia and can’t remember the secret at the heart of the world-changing conspiracy.
