SUMMER OF '98 From the author of "Mad As Hell" comes a funny, moving, unconventional exploration of a golden baseball season: the year of McGwire and Sosa; of the Little League champions of Toms River, New Jersey, standing in awe on the field at Yankee Stadium; and of Joe DiMaggio watching the Yankees have the kind of year he always had--reminding all that some still play baseball like they used to.
