"To say J is unlike any other novel Jacobson has written would be misleading: the same ferocious wit runs throughout. That said, comparisons do not do full justice to Jacobson's achievement in what may well come to be seen as the dystopian British novel of its times." -- John Burnside Guardian "A snarling, effervescent and ambitious philosophical work of fiction. Jacobson's triumph is to craft a novel that is poignant as well as troubling." -- James Kidd Independent "Jacobson once jokingly referred to himself as a Jewish Jane Austen. Here he reinvents himself as a Jewish Aldous Huxley - and displays mastery in the role." -- Max Davidson Mail on Sunday "Jacobson has crafted an immersive, complex experience with care and guile." -- Anthony Cummins Observer "J is a remarkable achievement: an affecting, unsettling - and yes, darkly amusing - novel." -- Matthew Adams National
