Just a word of caution, which applies to all rescues - I know the temptation is to get food into them, particularly when they've been without, but it really needs to be moderated. Same as with people, when they've been starved, you need to gently wean them on to their new diet. The potential shock to the system is a real risk, otherwise.
I'm sure you know all this, mind
It sounds like she's a real character, and the positive is that her character is intact - it's such a shame to find rescues with behavioural problems, owing to their treatment
I look forward to seeing this young madam introduced, and hearing how she gets on
