## Points of issue
First printing of the US edition (Disney-Hyperion, ISBN 978-1-4231-4060-3) is identified by the full number line that includes both 1 and 10 on the copyright page, in the interleaved form 1 3 5 7 9 10 8 6 4 2. Bound in red boards with the spine stamped in gold and purple endpapers; jacket art by John Rocco, with the printed jacket price present on the front flap.

## Is this the true first?
US first edition (Disney-Hyperion, October 2012), the recognized first for this American author; the US edition is the standard collector reference over the near-simultaneous UK Puffin release. First US printing was a very large run of roughly 3.5 million copies.

## Telling it from reprints & book-club editions
On the true first the number line runs 1 3 5 7 9 10 8 6 4 2; later printings drop the low numbers so the line no longer begins with 1. First-printing copies also show the red boards, gold spine stamping, and purple endpapers.
