Typos happen. The author reads through and gives a clean manuscript to the editor only for the editor to show just now messed up it still is. The author and editor fix the mistakes and it goes to a copy editor who finds even more. Then the galley edits come along and everything should be fixed, right? Nope.
And this is just about story inconsistencies, grammar, and flow.
I am solely responsible for the history and REALLY prided myself in taking that seriously. I researched saint days and weather patterns, period dress and beer recipes... I took the time and felt like a credible source when it came to history. Even if a reader doesn't like my story, at least I could say the history is sound.
When I discovered that I mislabeled Katherine Howard (I called her the third wife of Henry VIII) I cried. It's embarrassing and, regardless of everything I did get right, it completely destroys my credibility. It was something that didn't catch my attention in edits because this is an area of history with which I am ridiculously familiar. I didn't double check the big facts the same way I, for example, looked at period inheritance law for a peer who was not yet an adult because I trusted myself. In the edits, I didn't notice. This is, perhaps, an example of not seeing the forest for the trees (if cartridge pleating and such are the trees, the Tudor dynasty is the forest).
So let me put this out there:
I hope to republish this title and actively want to fix any errors for the next draft. I'm keeping records as they've come to my attention. If you notice something, tell me. I'll appreciate it, I swear. It will all go to making a better book. You can email me on Goodreads or leave me a comment here on my blog.
Just for fun, here's a graphic from a Horrible Histories book I picked up at Hardwick Hall years ago.
Thank you for your patience and understanding.
