What makes a character great? Can an author know or exert control over how a reader will respond to that character? Best-selling author Wally Lamb discussed the topic with Think host Krys Boyd ahead of his recent appearance at Arts & Letters Live. Lamb’s newest novel is The Hour I First Believed (Harper Collins, 2008). Think airs Monday-Thursday from noon-2 p.m. on KERA (90.1 F.M.).
