Identity, in Guy Ware's confident debut collection, is a mercurial thing. Lawyers paint conflicting pictures of an alleged terrorist; a city trader decides, without warning, to walk out of her life; flirting lovers take role-play to a new, existential, level. Whether living under a totalitarian regime or simply getting through the day in a grindingly predictable metropolis, Ware's characters struggle with the urge to redefine themselves, to start again, to reboot.
