Some bits that I remember:
I think the story was set in the UK and the man is a forest ranger and he's ex- special forces.
He lives as a hermit as much as possible.
The ex-wife's girlfriend had the family dog put down and let his family believe it was his fault.
His daughters really want him to fuck them and his ex-wife is cool with it.
The girlfriend ends up wanting to fuck him but has some serious trauma issues that cause her to freak out when they try.
They end up killing the baddies with crossbows.
I don't remember any character names unfortunately.
