The points of issue
First printing states 'First Avon Books Printing: May 1999' on the copyright page with a complete number line ending in 1. Black paper boards with gilt spine lettering, in dust jacket with the printed price on the front flap.
Is this the true first?
The US Avon hardcover (May 1999) is the true first, preceding the UK William Heinemann edition (also 1999). A signed limited issue exists but was not the trade first; verify the 'First Avon Books Printing: May 1999' line plus a number line ending in 1.
Telling it from reprints & book-club editions
A book-club edition is unpriced ('Book Club Edition' flap), typically smaller in trim with a rear-board gutter dot, and the 'First Avon Books Printing' statement and full number line are absent or altered.
