The first book of Gregory's Cousins' War sequence was first published in London by Simon & Schuster UK on 18 August 2009 as a hardback in dust jacket, ISBN 9781847374554 (1847374557), about 400 pages. The American hardback issued in New York in 2009 under ISBN 9781416563686 (listed under the Atria imprint) is a separate edition, not the UK first; check for the London imprint and the 978184737 ISBN prefix. The 2010 Simon & Schuster UK paperback (ISBN 9781847394644) and the 2022 reissue are not firsts. Ex-library copies appear on the market, sometimes without the jacket; confirm a first printing from the copyright page.
Simon & Schuster's British company, Simon & Schuster UK in London, identifies its books the British way: a first impression is shown by a complete number line on the copyright page.
Read the full guide to Simon & Schuster first editions, decade by decade, and check your copy's copyright page against it. Our number line decoder reads the printing from the row of numbers.
We have not yet confirmed the issue points that tell this first impression from later ones. Until we do, compare your copy's title page and copyright page with the publisher, place and year above: any later printing or edition statement means it is not this one.
