The Doctor's Wife
http://en.wikipedia.org/wiki/Death_of_Savita_HalappanavarBrings to mind the woman who died in Ireland because she was having a miscarriage, but doctors wouldn't remove the fetus because of anti-abortion laws.
My cousin carried to term a foetus with anencaphaly that she was told wouldn't survive more than a few hours after birth, because legally she wasn't entitled to abort it as her life wasn't in danger. She could have done what lots of Irish women do and travel over to Britain (Liverpool seems to be the place to go) and had it safely and legally aborted there without fuss, but for reasons I'm not sure about she chose to carry it to term.
It's a really sick situation to force someone into.
That is the sickest kind of cruelty to do to a woman. I can't even imagine the emotional pain your sister went through.
