Hardcover first edition, first printing and first hardcover edition. (Preceded by the Grafton paperback edition published in the UK.) Not a book club, remainder or ex-library copy.A fine (unread) copy in fine jacket. A clean, square copy in pristine jacket with price intact in protective brodart cover. Unusual to find copies in fine condition without previous owner's marks or inscriptions. An idyllic planet inhabited by a small community of humans is visited by huge colony ship carrying one million refugees from Earth. Clarke's first novel after publishing 2010: Odyssey Two. Very nice jacket illustration by Michael Whelan.
