The points of issue
The UK HarperCollins/Voyager hardcover (September 1992) is the true first: red cloth boards, priced jacket, no later-printing indicators. The first US edition is the Bantam Spectra hardcover (1993), identified by the number line 1 3 5 7 9 10 8 6 4 2 — it is a hardcover, not a paperback original, and is a year later than the UK first.
Is this the true first?
The UK HarperCollins/Voyager edition (1992) is the true first, preceding the US Bantam Spectra edition (1993) by roughly a year. The precedence is the key point; collectors seeking the true first must obtain the UK edition.
Telling it from reprints & book-club editions
No prominent book club edition is the trap here. The real trap is national precedence: the UK 1992 hardcover precedes the US 1993 hardcover.
