Poetry. The written ‘I’ is famously slippery, and never more than in this seamless collaboration that places the pronoun’s definition at its constantly decentered center. In four distinct sections, all perfecting a language rich in intriguing specifics and delightfully sharp surprises, the collection shows two contemporary masters in a brand new light, creating a new 21st century poet right on the spot, and one with a particularly promising and important voice.–Cole Swensen
