Looking for story--Australia-set, kidnap a wife

[becklin84]

I read this story so long ago that I don't remember all the details, but it was set in Australia and the man kidnaps a woman and brings her home and marries her. His father also did this so he doesn't think there is anything wrong with it. The wife grows to love her husband but calls her mom and is found by the police--later she visits the husband who had been sent to jail. At the end, I think she was pregnant. Any help would be appreciated--thanks in advance!
