London, Harper Collins / Voyager, 1992-1996. First Edition. First Impression. Hardback. A very good set. Volume one is signed without inscription to the title page, and dated '1992'. One of the finest works on Mars ever written. Certainly a key work for any collection of modern science fiction, and Robinson is one of the most important contemporary writers. Collectively, the trilogy has won two Hugos, two Locus awards, one Nebula and one BSFA award. Broderick & Di Filippo feature the trilogy in their excellent 101 Best Novels (1985-2010), comparing it to a 20th Century War & Peace, not simply due to the length, but the depth of research and sheer scope of it [Broderick & Di Filippo, p92]. In Andrews & Rennison's 100 Must-Read Science Fiction Novels [p112]. Three [3] volumes. A near fine set. Red Mars is foxed to the top edge, and the spine tips are bumped. Blue Mars has a few signs of handling wear. Green Mars is foxed to the top edge and has a little edge wear. Cover art by Mel Grant [7919, Hyraxia Books].
