I just don't like any of these people
It's a fairly straightforward plot – middle-aged teacher has affair with schoolboy – is observed throughout by her friend, the narrator (an older teacher).
But the characters are not terribly engaging at all – none is much more than two dimensional and it really did not grip at all. I was pretty unconvinced throughout by the author's attempt to get in the mind of an older woman.
Gawd knows how it ended up being Booker shortlisted
