I have received some valuable feedback to help me recognize the moment when my story may be really "done." While one fellow WD group member suggested that the third draft may be the charm, another person told me that a novel is complete when you get to the point of replacing and removing commas and periods - and nothing else. Yet a friend observed that there is no such thing as a completed novel - there are only various stages of imperfection.
So, while I am working on that.... I also started drafting a synopsis. When I first sat down to write my novel, I knew where I wanted to go with the story, understood its theme, and had a mental blueprint of the structure - although I would not have been able to actually name these as key factors. On the other hand, I had not an inkling about synopses, queries, pitches and all the other unpalatable aspects of writing with a goal of publication.
One week into writing a synopsis I discovered that drafting a query letter first works better for me - starting with a short plot summary and clarification of the theme came more natural and now I am building on those elements to create the various parts that comprise a synopsis.
Yes, queries, synopses all need to be done, but mostly, I think, I am focusing on these just so I can avoid another dreaded revision and face the possibility of my novel still not being done.
