Ever since he was a baby on the vine, Gideon Grape has never been shy about speaking up when things aren't just the way he likes them. He gripes in the summer and in the winter, in the morning and at bedtime, at breakfast, lunch and dinner, and nearly every moment in between. But when Grandpa Raisin comes for a visit, Gideon begins to see how constant complaining isn't the nicest thing to hear... and wonders if maybe it's time for a change.
