Grass is a 1989 science fiction novel by Sheri S. Tepper and the first novel from the Arbai trilogy. Styled as an ecological mystery, Grass presents one of Tepper's earliest and perhaps most radical statements on themes that would come to dominate her fiction, in which despoliation of the planet is explicitly linked to gender and social inequalities. Considered to be among her best works and hailed as "a splendid achievement, one of the most satisfying science fiction novels I have read in years" by New York Times Book critic Gerald Jones at the time of its publication, Grass was nominated for both the Hugo and Locus award in 1990. Interest in the novel continued, and it was included in the SF Masterworks classic science fiction paperback collection in 2002. Source: Wikipedia (en)
