The silly title here may mislead: this is an intriguing story about a ten-year-old worrier who needs to conquer fear and learn to stand up to her overeager mother. LuLu's first love is Little League, and she never misses a game or a practice. Then she falls into the hands of a toddler named Jenny--or, more literally, Jenny jumps out of a third-story window into LuLu's arms. Jenny's teen-age mother, Tilda, has robbed her own mother and run away from home, but now the money is almost gone. LuLu, understanding the value of game plans and strategy, helps Tilda by adopting the mother-daughter team and housing them at her grandmother's house. In the meantime, she must reluctantly cope with the media attention caused by her heroic ""catch"" of Jenny, without giving away Tilda's identity. In this book of one idea--that heroism may come to those who least expect it--comic moments are served up like a few shiny coins: scenes featuring LuLu's endless fears (of strange food, of riding her bike no-handed, etc.); and those showing Tilda's predicament as a teen-ager who has taken on adult responsibilities far too soon. Despite some loose ends and occasional clumsiness, this offers a bit of effervescent fun.
