# Is "The Hammer of Thor (Magnus Chase 2)" by Rick Riordan a First Edition?

> **Quick answer.** A first edition of The Hammer of Thor (Magnus Chase 2) by Rick Riordan (Disney-Hyperion, 2016) is identified by: Disney-Hyperion hardcover with 'First Edition' stated and a number line on the copyright page running down to 1, dated October 2016. The US Disney-Hyperion hardcover of October 4, 2016 is the true first.

**Checklist — a true first has these:**
- Disney-Hyperion hardcover with 'First Edition' stated and a number line on the copyright page running down to 1, dated October 2016
- The binding is green cloth boards with silver spine imprinting and a silver 'MC' monogram stamped on the front cover, with olive-green endpapers, beneath a pictorial dust jacket
- A separate Barnes & Noble exclusive first edition exists with the same ISBN family but bonus content, including an illustrated 'Message from Floor 19'; the standard trade first lacks that bonus section
- Later printings drop the 1 from the number line
- Publisher imprint reads Disney-Hyperion
- Not a book-club edition (see below)

## Points of issue
Disney-Hyperion hardcover with 'First Edition' stated and a number line on the copyright page running down to 1, dated October 2016. The binding is green cloth boards with silver spine imprinting and a silver 'MC' monogram stamped on the front cover, with olive-green endpapers, beneath a pictorial dust jacket. A separate Barnes & Noble exclusive first edition exists with the same ISBN family but bonus content, including an illustrated 'Message from Floor 19'; the standard trade first lacks that bonus section. Later printings drop the 1 from the number line.

## Is this the true first?
The US Disney-Hyperion hardcover of October 4, 2016 is the true first. The UK Puffin edition, with different cover art, was published the same day, October 4, 2016, so there is no earlier overseas edition.

## Telling it from reprints & book-club editions
Later printings drop the 1 from the number line.
