Gr 3-5-- Juan is attacked by a trio of grade-school bullies because of his Hispanic heritage, and Billy, who is too frightened to come to his aid, subsequently has a hard time winning Juan's friendship back. Apparently, Juan's family has been made the object of childish hatred as an on-going thing. Billy has troubles at home too: a stepfather he dislikes, a mother whom he feels has betrayed him by remarrying, a teenaged punk stepsister, and a baby half-sister who is a whiny misery. Things start looking up when Billy and Juan win the three-legged race at school: the bullies back off, Juan's family appears to be prospering, and Billy's family turns out not to be so bad after all. Poorly plotted events hardly seem connected. The boys' dinosaur club is linked with little but the title. Characters are flat and unbelievable. The stepfather starts as a bigoted villain, and then changes his opinions for no discernible reason. The wicked stepsister drops her punk persona and inexplicably turns sweet and kissy. Mother, who is struggling through college, suddenly decides to seek political office. Juan's relatives are caricatures of passive victims and are unreasonably and disgustingly cheered by the condescending friendship of an anglo family. If all this weren't confusing enough, the characters are made to speak in a strained hip/cool lingo that frequently goes beyond mere tiresomeness into vulgarity, as when Billy speculates offensively on his parents' sex life. Let the dinosaur club collapse for lack of members and be buried with the fossils. --Ruth Semrau, Lovejoy School, McKinney, Tex.
