by Piers Paul Read. Lippincott, $10.00. With the approval and cooperation of the survivors, Mr. Read has reconstructed the story of that Uruguayan Rugby team that was stranded in the high Andes by a plane crash. Of necessity, those who lived resorted to cannibalism. The account that Mr. Read has skillfully pieced together is both gruesome and touching. In its relentless service to truth it is also somewhat longer than art or necessity requires. Illustrations.
