I was an over-achieving, high stress kid in high school (a million years ago) and found this to be a pretty realistic depiction of that experience. I definitely don't thing this is a good for everyone, but it would be a good one for high achieving teens who're obsessed with perfection. I liked it quite a bit. FYI: The ending is very open ended, which I like, but I know isn't everyone's thing. 
 A note: There's a new family that comes to town in this story that's bizarrely self-identified as British and yet they're clearly of Irish extraction. They were born in London and have lived all over the world, but I've known enough folks who've been part of the Irish diaspora in similar ways and they'd never describe themselves as British. They'd say something like Irish but born in England. For whatever reason, this bugged me.
