The retired admiral James Stavridis teamed up with Elliot Ackerman, a journalist and former Marine, to imagine how, in the shadow of an increasingly tense relationship between the U.S. and China, a small incident in contested waters could spiral into catastrophe. The result is “2034: A Novel of the Next World War.” The book is a thriller, and also a cautionary tale about a failure of military planning: “We have plenty of intelligence,” Ackerman says. “What we often lack is imagination.” And Torrey Peters describes how her book “Detransition, Baby”—a dishy novel on a taboo subject—aims to move beyond the marginal spaces in which trans writing has flourished, into mainstream success with a major publisher.
