Book excerpt: In the mid-1960s, British science fiction and fantasy were convulsed by the "New Wave." This movement emerged from the SF magazines edited by John Carnell. Such brilliant NEW WORLDS and SCIENCE FANTASY writers as J. G. Ballard, Brian W. Aldiss, John Brunner, and Michael Moorcock heralded the rise of this new kind of fantastic fiction. John Boston and Damien Broderick's concluding volume of their critical trilogy examines the history and development of these important magazines--and the fiction that they championed. By the end of this period (1964), Carnell had set the stage for that major development in UK science fiction--the new wave adventures of the transformed NEW WORLDS, under the editorship of Moorcock--and had himself shifted gear into the next mode of SF publishing as editor of the paperback anthology series, New Writings in SF. Boston and Broderick's series will become the definitive critical histories of these important British magazines. Complete with indices of names and titles cited.
