Fans of the four earlier books about Becky will be delighted with this sequel in which she and her best friends, Kyra and Mel, make a quartet with the addition of Rainbow Rothstein--a self-assured newcomer to their fourth grade in Brooklyn's Park Slope, who has appeared in several commercials and whose mother is a talent scout. Like a comfortable visit with old friends, this starts with a roundup of news. The pace quickens when Mrs. Rothstein wants Becky--who hopes to be an artist like her dad--to audition for a crayon commercial. The first audition, when the crayons are make-believe, is a success, but it leaves Becky out of sorts with her old friends. The callback is a disaster--Becky fails to disguise her disgust with the shoddy project she's trying to demonstrate--but its aftermath is a reconciliation that is far more important to Becky than her disappointment. As before, Orgel has a sure grasp of Becky's concerns, not only her friendships but her place in a family in which the parents are amiably divorced; her glimpse of the vicissitudes of the talent market is also fair and realistic. A pleasant story, sure to engage its audience.
