The fantasy world we build around professional athletes took a serious hit when this NBA superstar announced his HIV infection and retirement. Here, a simply phrased account of Johnson's record-breaking basketball career is sandwiched between an analysis of the announcement's immediate effects and a look at his other career as a successful businessman. This is timely but superficial: the ``If I can get it, anyone can'' message is delivered, but readers will not learn much more about AIDS or the AIDS crisis, nor are they directed to other books or organizations that might help. Marginally useful for assignments; better efforts are probably in the pipeline. B&w photos. (Biography. 11-13)
