Needle in a Timestack is Robert Silverberg at his very best-intelligent, inventive, and visionary. This collection showcases his talent for thought-provoking science fiction, ranging in themes from time travel to space travel, the media to mortality. In the titular story-under development as a feature film by Oscar-winning screenwriter John Ridley-a jealous ex-husband warps time in a vindictive attempt to destroy his former wife's new marriage. Thirty-one identical sons have a shocking surprise for their mother in 'There Was an Old Woman.' The prophetic 'The Pain Peddlers' depicts reality TV in a way that allows viewers to revel in a voyeuristic, adrenaline-fueled rush. Also included are Silverberg's Hugo Award-winning 'Enter a Soldier. Later: Enter Another,' and the Locus Award winner 'The Secret Sharer,' a Joseph Conrad-inspired tale of a ship captain drawn into a strange alliance with a stowaway.
