What could be more innocuous than grass? Or more idyllic than a world covered with a wind-whipped ocean of verdant plains? But the planet Grass conceals horrifying secrets within its endless pastures. And as an incurable plague attacks all inhabited planets but this one, the prairie-like Grass begins to reveal these secrets - and nothing will ever be the same again ... Considered to be among one of Sheri S.Tepper's best works, Grass was nominated for both the Hugo and Locus awards. It explores ideas of colonisation, class and sits as part of a rich culture of feminist SF. In 2015, Tepper received the World Fantasy Award for Life Achievement.'A splendid achievement, one of the most satisfying science fiction novels I have read in years' - New York Times'One of science fiction's premier world-builders' - The Encyclopedia of Science Fiction'Tepper delves into the nature of truth and religion . . .in her compelling story' - Publishers WeeklyWelcome to The Best Of The Masterworks: a selection of the finest in science fiction
