Kate Tempest's début is the expansion of a story she threaded through her 2014 album of protest hip-hop, Everybody Down. In its transformation to novel form it has become part love story, part state of the nation, part existential treatise. This much-admired spoken-word artist's venture into prose is a compelling attempt at capturing the restlessness and anger of disenfranchised 'millenials' (Tempest was born in 1985), yet it is also surprisingly unimaginative in its style, and frustratingly tangential.
