FROM THIS DAY FORWARD

John Brunner's science fiction constructs have a crepitant immediacy perhaps because tomorrow might almost be today and because speculation is compounded with suspense. The lucky 13 here include ""The Biggest Game"" in which a congenital womanizer is stalked not only by husbands and private detectives but also men in black; a story of a too successful young man who can avert trouble by extrasensing it ahead; the life = death = doom which is ""Wasted on the Young""; a variant Judas story, a Rip van Winkling ""Fairy Tale,"" and a Naderesque ""Factsheet"" with its clairvoyant revelations; and do not miss ""The Vitanuls"" in which a saintly Indian deliverer of thousands and thousands of infants finds that the world has run out of souls. . . . Genuine startlers.
