Today show co-host and meteorologist Dreyer's sequel to Misty the Cloud (2021) finds Misty celebrating her birthday, which she shares with human Clare. Clare is having a birthday party. Unfortunately, she's sharing the party with her younger brother, Tyler, whose birthday is approaching. Clare wants Tyler's guests and party paraphernalia to stay on their own side of the yard. But that may be moot when it starts to rain. The cause? Misty's party game of One, Two, Three, Can't Catch Me!, which also gets in the way of the sunbeams' game of Funny Sunny. When sunbeam Raye and Misty finally compromise (cue a bit of didacticism) on a game that equally suits both clouds and sunbeams, the result--a rainbow--not only allows the humans' parties to go forward but makes for "the perfect decoration." And the icing on the cakes? The siblings ultimately, though a bit facilely, enjoy a truly joint party. (The clouds and sunbeams demonstrate compromise much better than the humans.) Backmatter includes some weather facts and terms and a rainbow-making activity; both seem a bit above the target audience's age range. As with the prior title, the illustrations are the true stars, their vibrant colors and delightful anthropomorphized characters stealing the thunder from the too-easily-solved social problem. Clare and Tyler are light-skinned; other human characters are diverse. (This book was reviewed digitally.) A slight improvement on the first title, but separate books on rainbows and compromise would better serve kids. (Picture book. 4-8) Copyright (c) Kirkus Reviews, used with permission.
