My editors felt that things could be improved on my manuscript so I get to revisit the world again. The important thing is to ultimately give the reader the best read possible. One of my mistakes was to make an important confession triggered by an external event, rather than an internal to the relationship event. The external event happened to the heroine BUT the whole thing didn't move the relationship forward. I also had a two seperate turning points that would have been better as one turning point.
Sometimes, the mistakes in a manuscript can't been seen until they look at the whole thing.
Disappointing -- yes in a way but on the other hand I want to give my readers the best possible read. It is good to know that my editors care enough to send the manuscript back and say -- we know you can improve on this.
