In this entry in the new Cobble Street Cousins series, nine-year-old cousins Rosie, Lily, and Tess, whose three sets of parents are all away touring with a ballet company, open a business and play matchmaker for Aunt Lucy, with whom they're living. The girls have split up the attic of their aunt's house on Cobble Street: Lily's area has yellow curtains and a table for writing, Rosie's bed is under the stained glass window, and Tess has a small record player to listen to her favorite Broadway tunes. When Lily comes up with the idea of starting a cookie company, the cousins put up posters and soon orders are rolling in. One of their customers, Michael, has a crush on Aunt Lucy, who runs a flower shop. The girls bring Michael and Lucy together, and move on to their next plot--to plan the wedding. In an era of CDs and highrise apartments, this throwback is a surprising comfort; there's an enchanting purity to Aunt Lucy's geranium-ensconced house. To enter into these pages is to find a street, and home, where children are happy individuals, far removed from school shootings and drugs. Halperin's delicate, detailed black-and-white illustrations of the girls, their posters, and even their cookies are perfect for this tidy volume.
