One step up two steps down

Down the upI’m currently going up the down escalator of life (or down the up?).
Because other things are getting in the way of the writing at the moment when I actually had some time to sit down at the laptop I realised I needed to re-read the whole 42,000 words to regain the threads. This re-read showed up some inconsistencies and repetitions which needed clarification and re-writing so, despite getting up at 3.15 one morning, incidentally completely confusing the cat,  I find myself no further forward in telling the story than I was last week.
Incidentally it became clear that the working title A Different Coast was not going to work so those hours I normally spend lying awake thinking what will be written the next day have, instead, been spent trying to think of the right title.
It is the sequel to Her Parents’ Daughter so I was thinking the title has to reflect that somehow but all those that sprung to mind (A Father’s Revenge and Three Fathers’ Sons etcetera) were either unwieldy or already taken.
At the moment I’m thinking of it as Tit for Tat but can you have “Tit” in the title of a book? I then tried Tip for Tap apparently the original saying and may go with that for the time being anyway.
Hopefully (in all senses of the word) progress will be made before my report to you next week.
