Digging deep into the story line

When a writer finishes the second draft, it is time to read slowly and dig into the story line to determine the holes that might exist in the story. It is time also to ask yourself is the character believable along with being consistent with himself? Does he change back and forth as the story progresses?  I know my Character John Strum in "Saddle Spur"goes from being a naive young man to a harden young man but is consistent in keeping his word even when he really would not like to keep it. John believes his word is bond and has to die to get out of his wedding vows becoming another person. I believe that the turmoil inside John is accurately portrayed in the book especially when his wife tries to kill him to get out of the marriage. He just couldn't bring himself to shoot back at her.
    When a writer is able to convey his emotions; you know it is a good book even written in the third person. Do you agree? Talk back, I'm listening as always. I would like you take on this subject. Have a great day.
