I was not very attracted to the subject at the start, and I am not persuaded that this, on arrival. Finally, it is a novel that falls fairly quickly into banality. The first good idea, one that saves a little book in my opinion, is choosing a narrator of five years and make him tell his reclusive world with his child vocabulary. The second (good idea) is to have built this citadel of maternal love around the child, an almost palpable intelligence citadel where, under a naive aspect, everything is meticulously thought to protect little Jack. Then the rest was a bit bland, slightly more agreed predictable. I was up late, but without much conviction.
