This is an ebullient, irreverent and deeply serious novel in the noble tradition of Mark Twain, Sinclair Lewis (especially Babbitt and Elmer Gantry) and John Kennedy Toole. Sam Lipsyte certainly hits his prime target — the cultish behaviour around mindfulness, motivational speakers and pallid spiritual beliefs — but one of the joys of the novel is that over and above that there is a scatter-gun sniping at various fads.
