Whta's the name of this book?

Ok I know I'm giving little here, maybe too little but here goes anyway.
A few years ago I read a book that I really liked but apparently not enough to remember the name or much detail.But I would like to read it again- that much I do know.

This is all i remember about it:

A girl takes off from work and goes to live in this house by the sea….her dads? I don’t know. It’s a fixer upper. There’s a facility outside to wash clothes. She gets fish and chips the one day... There is a cliff….? Someone jumped off it?
She meets an old man who lives in a rented house I think? He makes her tea… The house might have been left to her by her dead dad, her sister got jealous, she tried to sue her for it and eventually comes to visit?
The girl meets a guy…

also i think she doesn't have a very good relationship with her mom, who remarried a guy just for his money. The mother prefers her sister who is perfect.
I think the house was actually her dad's love nest with another woman who bore his child, and this woman didn't know that her lover died...?

I know its vague and random but if anyone has any idea the name and author...PLEASE tell me!!!
Urgh! *scrunches forehead in frustration*

Ahhh typo in the title, sorry
