Isla loves to paint Sky and all her glorious multicolored moods! Sometimes Sky is vast, bright, and blue; sometimes she is dark and thunderous, her raindrops reflecting the town below. Isla loves all Sky's moods and tries to capture the variety in her paintings. When Sky rains or clouds over, however, all the other townspeople grumble and moan. Sky decides she should just try to be happy all the time, so people aren't cross with her. But this is harder than it looks and soon the world below--and Isla's paintings--start to suffer. Can Isla convince big, bold Sky to let all her feelings and colors show? What happens to Sky when she is on the brink of bursting?.
