The Wisconsin Book Festival is hosting best-selling author and multi-time Pulitzer nominee Joyce Carol Oates to discuss her latest anthology, Zero-Sum on September 28 at 7 p.m. In this powerful collection, zero-sum games are played for lethal stakes as Oates creates a world of thwarted idealism and ever-shifting identities. Copies of Zero-Sum will be distributed for free to all attendees courtesy of a gift from the Cheryl Rosen Weston Estate.
