On Monday, Salon ran a provocative essay by Rahna Reiko Rizzuto, called “Why I Left My Children.” Since then, Rizzuto — whose memoir “Hiroshima in the Morning,” about reporting on the legacy of Hiroshima as her marriage fell apart, is a finalist for the 2010 National Book Critics Circle award — has appeared on MSNBC and “The Today Show” (video below) to talk about she believes we should rethink traditional ideas about motherhood. She has more appearances to come; we’ll keep you updated.
