What happens to them at the end?

I'm guessing the daughter will either go into the bee keeping business with the lady, who was getting up there in years and close to retiring, and the daughter will overtake it 100%.
Or else she does odd jobs around the camp earning a few bucks here and there or as a trade off for rent with some upkeep of the grounds.
She might get bored at some point and eventually move away or meet a man who she leaves with.

As for the dad will he ever return to try and find her?
I think at some point he will.

I suspect she will have moved on and he will have to try and track her down.

(He should have stayed and been homeless in the woods since they were OK with that other guy who was.)
