Fliss is on the way to visit her grandmother in Wales - the grandmother who she doesn't get on with - with her mother who is recuperating from chemotherapy. But her mum is getting better, that's the main thing, so Fliss can concentrate on being grouchy and not looking forward to meeting her grandmother Margot, who is so cold and always so unforgiving of Fliss's every mistake . . .

How can you hate someone in the present and love them in the past?

Fliss's mum needs peace and quiet to recuperate from a long illness, so they both move to the countryside to live with Margot, Fliss's stern and bullying grandmother. Life on the farm is tough and life at school is even tougher, so when Fliss unearths Margot's wartime diary, she sees an opportunity to get her own back.

But Fliss soon discovers Margot's life during the evacuation was full of adventure, mystery . . . and even passion. What's more, she learns a terrible secret that could tear her whole family apart . . .
