In working on my current Lex Atreus e-book I wanted to be sure I wasn't conflicting with an earlier work, so I reread "The Dragons of Despair."
And discovered my story was unstuck in time.
Y'see, each chapter begins with a date stamp and, well.... For unexplained reasons mid-novel it remains 23 October for three days in a row (despite the fact that dialog establishes a week has passed between 23 Octobers #2 and #3), then it becomes 24 October, then it jumps back to 19 October, then 23 October for another day before resuming normal chronology.
Never mind me not noticing and the editor not noticing -- we're professionals qualified to make mistakes like that. But this e-book has been out since 2006. It's been downloaded thousands of times. By fans who -- as a general rule -- live to parse inconsistencies.
And nobody noticed?
Maybe "downloaded" is not the same thing as "read"?
