The account of her experience after the fall is the strongest section of the book. It is gripping, and an achievement all the more remarkable as in fact very little happens. Time passes. Pain continues. Water runs out. And Nelson thinks. Her particular circumstances allow for an intimate examination of a brain under stress. She thinks about life and her regrets. One is obvious: “The amount of time that I spent – that I wasted – pissing about on the internet.” ...It is difficult not to warm to Nelson, and I waited anxiously for her rescue. She isn’t always the most lyrical or stylish of writers, but she is genuine: determined that she will survive, “because this is not how my story ends”. In fact it is her internet habit that saves Nelson: her absence from Facebook and Instagram is noted and triggers an alarm that leads to her rescue that leads to hospital and a can of Diet Coke that she has dreamed of constantly for the four days in the gully.
