The author's loving absorption in the doings of little girls give this book a facsimile feeling as to actual play and school activities although an overprotective, adult sentimentality sometimes gets in the way. Eight-year-old Polly and her friend Jenny have a lovely time in Polly's new house, although moving means a separation during school hours. There is the excitement of exploring, playing new imaginative games and Jenny's visits. However, when Polly's neighbor, Tilly, who comes from a poor and unsympathetic home, intrudes upon their games, cruel juvenile black-balling, begins. It is Polly's mother who finally investigates when Tilly burns her hands rescuing a painting of Polly's she had spitefully stolen, and lectures the girls on generous behavior in a weepy session. A quiet, happy family story, although to our mind, too much adult participation and direction. Most young readers are more interested in identifying themselves with the heroines than comparing real and fictional mothers.
