Blue Mars

Kim Stanley Robinson · HarperCollins / Voyager (London) · 1996

The UK HarperCollins/Voyager edition (1996) precedes the US Bantam Spectra edition (also 1996) and is the true first. Both are dated 1996, so confirm by imprint and jacket: the Voyager copy carries the '1 3 5 7 9 8 6 4 2' number line and no 'First Edition' line, whereas the Bantam Spectra copy states 'First Edition' with a full descending number line.
