In her first novel for children, Greeson adds one rather odd touch of fantasy to an otherwise realistic story about a fifth-grader who has given up brushing his hair. Kenny Wild's classmates (especially the girls) find his disarrary unsavory. His parents have tried bribes; now they're ignoring the problem--although they're also instrumental in sending him to the school psychologist, who gives him a wishing stone. After Kenny wishes for truly wild hair, he gets one--which migrates from place to place. This is embarrassing: when it's in his mouth, he has to take a vow of silence; when it's on his foot, his shoes don't fit. Finally, he simultaneously tries a cure he finds in a book--rubbing the hair with a dead cat--and combs his hair. End of problem. Smoothly told, and with a good eye for kids' behavior; but the tall-tale plot is slim, bizarre, and just not very funny. The stolid full-page drawings aren't much help.
