This seems to be a ‘love it or hate it’ kind of book: literary Marmite. The omens were good. The publishers managed to get a cover blurb from Margaret Atwood, and implied that this was a new feminist classic: the Handmaid’s Tale for the next generation. It was longlisted for the 2018 Booker Prize and, to give credit where it’s due, the writing is beautiful – but in the way that an art-house film is beautiful: stylised and a little self-indulgent. Hyped as a fable for the #MeToo era, this unsettling story centres on three sisters living on a remote island: Grace, Lia and Sky. They have been raised in isolation from infancy, protected from the poisonous toxins of the mainland, and treated with therapies to contain their burgeoning emotions. Complicated rituals devised by their New Age parents protect them further. But what are they being protected from? No one will explain. One day, shortly after their father disappears, they face an unprecedented threat. Two men and a boy wash up on their beach, disrupting the balance. The island’s prophylactic seclusion will never be the same again.
