Rachael is on an Antarctic expedition when she becomes isolated and receives a BBC broadcast reporting a nuclear attack.
She will try to survive while facing loneliness, her memories and the elements. We learn how she got there through her recollections and her diary which is an explanation of her reasons for being there and not with her husband Adam and her daughter Izzy. During the novel we can see how although sometimes she seems to faint, but Rachael is a fighter and never gives up.
The narrative rhythm goes from more reflective at the beginning to accelerate with the events creating the same sense of urgency that our protagonist feels.
A fantastic and different thriller with an interesting twist and where the main enemy is nature.
