From Coretta Scott King Award–winning author Patricia C. McKissack comes a humorous and poignant picture book about the right time to tell the truth. “Tell the truth and shame the devil,” Libby’s mama has told her. So whatever is Libby doing wrong? Ever since she started telling only the truth, the whole world seems to be mad at her. First, it’s her best friend, Ruthie Mae, who gets upset when Libby tells all their friends that Ruthie Mae has a hole in her sock. Then Willie gives her an ugly look when she tells the teacher he hasn’t done his homework. It seems that telling the truth isn’t always so simple. Can Libby figure out what it really means to be truthful and make amends?
