Looking For A Book on a woman who runs away and starts new life she disappears to the coast of Ireland Donegal. And she is from Scotland
after her mother has a stroke and she wins a lot of money on a horse it is also a story about a police woman who looks for her and a baby that was disabled that they killed years before I enjoyed it I cant remember the title or the author but I got it in waterstones 2 years ago and it was 3 for 2 in fiction so it is quite recent. Any ideas no luck on google Someone must know
