Hi, I started reading a book years ago that went missing soon after, so only have vague memories of the beginning to go on. I think there was some sort of accident that released poison or possibly there was a virus, one woman left but her friend didn't. The woman who left went back and had to break through barbed wire (possibly with a man, maybe a soldier but not certain) to get back to her house I think to collect belongings, she saw her friend who had stayed behind. The friend was delighted at how much weight she was losing and wouldn't leave, I think possibly her mum was dead or dying from the virus/poison... And that's all I've got. Does it sound familiar to anyone please? Would love to find it and finish it.
