Notes: • "First Pocket Books Science Fiction printing July, 1985" • First printing by number line 10—1 • The artist is not credited, Boris is on the artwork • "This was revised part way into the print run so there are apparently two versions, the first has an embossed cover." - from Locus1 • A quick comparison of the first and last 50 pages between the first Canadian edition [not embossed] and the first US edition [embossed] shows no differences in text • By the fourth printing a section of text on page 41 had been completely excised • Printed in Canada but retains the US price code in the barcode block
