Gr 3-5 In this sequel to Millie Cooper, 3B (Dutton, 1985), Millie learns that growing up means having to take some chances, and she faces a few challenges which bring her out of the protection of her family. She wants a bicycle so she enters a radio contest and tries to sell newspaper subscriptions with very little luck. She is afraid that she will get few valentines, so she tells her friends not to send her any and, to her dismay, they listen to her. She finally builds up the courage to recite one of her favorite poems to her class. Her success in this endeavor leads her to believe that she can continue to take risks. Millie is again a complete character with some fears, friends, and lots of humor. The other characters, especially the boys in 3B and Millie's supportive mother, are also believable. Although this is set in 1947 in Chicago, the story does not depend on its setting. Readers who enjoy Ramona (Morrow) and Anastasia (Houghton) will want to meet Millie Cooper. Margaret C.
