It's not Anastasia, it's really well written and rather than being shocking as such, without trying to post a spoiler, you end up thinking differently about the whole thing - it's not only a tragedy for the little girl who dies, but for the other two too - and even ends up being almost a "good" thing for the one from the deprived home. It's really thought provoking. There was one bit that got to me, later on in the book, but it had actually nothing to do with the child or any children, and was only a tiny scene - just an AWWW nooooooooo moment but not utterly heartbreakingly awful iykwim.
