This should have been a DNF. I couldn't make myself interested in Grace or Becker. I did love the descriptions of Eris, the remote Scottish island where a famed artist moved. All of the people involved were shallow, selfish, and petty. The second someone pursued a bit of freedom or was happy in their lives it was shown as a bad thing.
"All is fair in love and war, and friendship is love, too, isn't it? And a kind of war sometimes as well."
I'll admit I was disappointed in the predictable twist. Of course the "ugly" lonely woman was jealous and started killing people. It just felt so unoriginal. Of course a woman who is a capable doctor couldn't be happy in her life if her friends aren't completely obsessed with her. Ugh. I just didn't love that ending. 3h
