The French Surrealists invented a game called Exquisite Corpse to write collaborative poems, and thus the title of Denis Duhamel and Maureen Seaton’s new collection, Exquisite Politics, hints at its collaborative nature. In poems that speak at times in a breezy, conversational style, and at other moments with taut intensity, Duhamel and Seaton probe the mysteries of relationships, personal histories, and issues of sexual and political identity.
