"Be patient; it will pay off"
The detail is tedious. Everyone is so terribly sensitive, and trivial interactions take pages. But every few pages there is a "ping," of something not right, or a growing realization that there are large things missing in this detritus of kids at a boarding school fussing about their feelings. Then you slowly realize what is missing, and some of the trivial events reappear with deeper meaning. Two-thirds of the way through you realize the importance of the author's emphasis upon tedious little spats and hurts and crushes, and then the reader (who is fine) annoys you because she can't read fast enough as the horror mounts and the jigsaw gets completed. It is not science fiction at all, as some say; it is all at hand and little prevents society from seeking this path to health.
