When Mira Jacob’s son was 6 years old, he started asking questions about what it meant to be biracial in America. And she found that answering those questions led to some interesting conversations. Jacob started keeping track of those conversations in a graphic memoir called “Good Talk.” The book is this year’s Multnomah County Everybody Reads selection. We talk to Jacob in front of an audience at Lincoln High School. She’ll also be speaking at the Arlene Schnitzer concert hall Thursday, March 10th at 7:30pm.
