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. Children will sympathize with Libby as she struggles to figure out that even though it's always wrong to tell a lie, there's a right and a wrong way to tell the truth. Giselle Potter's naively stubborn illustrations perfectly capture this humorous and poignant story by award-winning author Patricia C. McKissack.
