Mr. Either/Or: All the Rage is high-thrills poetry; set in a funhouse Manhattan apocalypse; a mixture of pregnancy, sleep-training and violence. A sequel to “Mr. Either/Or” (2017), this verse-novel features “you” the reader as a secret agent in Manhattan in which poetic rhythms cue and accompany action-scenes. “You” and your girlfriend Li-ling Levine save the world from villains fighting for anarchy and the end of the human race.
