Mediaeval Novel, Final Revision.

I wrote my mediaeval novel set in the reign of Edward II of England a few years ago. Since then, I five of my novels have been published and a sixth has been accepted for publication. In between writing those novels and dealing with lots of 'writerly' matters as well as the demands of daily life, I have dipped in and out of my mediaeval novel. Now, I am determined to finish the revision, but the main problem is that I have dipped in and out of it so often that I see what should be on the page, not what is actually on it. Sometimes it seems as if it will never be ready to submit but, fingers crossed, I shall submit it in June.
