Nicola Barker’s H(A)PPY is a work of vaulting ambition. It is deathly serious but played out with the lightest of touches. She takes the vapid discourse of social media blather, with all its ‘likes’ and ‘favourites’, and extrapolates madly to make a language for an utterly believable future world, a world enslaved by the blandness of its technology. Line by line, the novel carefully builds its music and teases out its crazed riffs. It’s very funny but there are pockets of great eeriness, and of savagery even. It’s a novel-as-object, too, with a typography employed as visual code, but its design always has a narrative purpose. Only a writer of uncanny ability could bring this novel to such memorable, pulsing life. It’s very moving.
