Indeed, do not fear the full-stop. Recognizing your foibles as a writer is the first step to conquering them. On the other hand, I don't any writer cranks out perfect prose. History is riddled with those who had a love of the run-on sentence. Hemingway comes immediately to mind, and he didn't care much for punctuation, either.

Rian had lovely suggestions for Gabriel's voice and dialogue structure. I would have given the same advice.

Personally, I can't wait to read this book. Because I know you're going to rock it hardcore.
