I spent the next several hours, until the wee hours of the morning, re-writing several portions of the manuscript, as one thing invariably led to another. This morning I re-read and re-edited what I wrote last night because I knew I had been too tired to do my best, but at least I had gotten the changes roughed out.
This just goes to show how important it is to edit and re-edit until you are SURE you have things right. I don't know if a professional editor would have caught this -- probably yes, but many readers did not -- but I have done my share of complaining about poorly written published works, and, as such, if I had published this one the way it was, I would have been embarrassed. Once your work is out there, you can't take it back!
