For some reason my publishers have been unable to get on top of this issue for the last three or four novels. It first happened when I submitted a long list of final corrections before the deadline for The Endless Forest, and somehow they just never made it in.
Advance Reading Copies (ARCs) have a big sticker on them saying that the text is not final and should not be used for quotations. This is because they put the ARCs into circulation before the final proofreading.
For Where the Light Enters, things really went wrong. First Australia printed the ARC as the book, no corrections. The ebook versions will have the corrections, but not the hard copies are full of little burps. My heart fell when I realized this. I don’t know how it happened, but I am not pleased.
Then a whole list of corrections somehow — once again — didn’t get incorporated before the novel went to press for the hardcover edition here in the U.S. Yes, those corrections were incorporated into ebook and audio editions, and they will be included in future hard copy editions, but if you spent a big chunk of money on the hard cover, I would much prefer that you get the final product.
I am notoriously bad at proofreading my own work, but the publisher still hasn’t quite grasped the depth of my text-blindness. So apologies, all around. Mea culpa.
