HALCYON, Elliot Ackerman's new novel, received an abundance of rave reviews following its publication last month. BookPage reviewer Harvey Freedenberg writes: “With the passing of Ward Just in 2019, the literary world lost a fine writer who was comfortable grappling with the moral dilemmas surrounding the exercise of power and the lives of those who wield it. Journalist and novelist Elliot Ackerman’s fifth novel, HALCYON, suggests that he may be one of the inheritors of Just’s preoccupations. Blending alternative history with science fiction, Ackerman artfully explores several provocative issues that have become flash points in contemporary America…Ackerman prefers challenging questions…over convenient answers. With this choice, he leaves ample room for readers to engage in leaps of imagination as bold as the ones he’s undertaken. Anyone who accepts that invitation will come away from this ingenious story with fresh ideas of what past, present and future truly mean.” For The New York Times, reviewer Stephen Markley calls the book “idiosyncratic and engrossing throughout,” and an “expert juggling act.” For The Washington Post, reviewer Mark Athitakis writes: “HALCYON is an entertaining thought experiment, and Ackerman writes with a gentle, graceful style…Ackerman delivers a potent critique of the what-if nature of talking about history…[and] as much as any working novelist today, is invested in getting the facts of war and history right.” Ackerman was also profiled by Emily Bobrow in The Wall Street Journal. Knopf published the book on May 23, 2023.
