I thought it was pretentious, overwritten, self-indulgent and a let down to the reader who soldiered on to the end - because there was no end!
The premise was interesting, family on holiday in a fabulous but remote holiday home when strange things begin to happen and intimations of some disaster in New York where they normally live. The owners of the property arrive and expect to be able to stay while they try and decide what's going on with no media working and their phones out of action.
However the characters were so difficult to empathise with, and in some ways quite unpleasant, there were endless conversations, very little happened and after what seemed like an eternity of reading it just finished with no resolution and no prospect of one.
Why did I read it to the end? I'm meeting friends to talk about it!
