A Dance of Devils

In the wake of a devastating Christmas Eve electromagnetic pulse attack that plunges America and Europe into darkness, a coordinated assault by a new axis of adversaries threatens the survival of the United States. Nuclear strikes devastate major cities while enemy forces pour into the homeland, advancing on critical strategic targets—including the hardened underground complex at Mount Weather, where the remnants of American leadership and military command are concentrated.

From the decks of a rusting cargo ship in the Atlantic to the suburban cul-de-sacs of Northern Virginia and the battle-scarred fields of the Shenandoah Valley, a diverse cast of defenders—battle-hardened Marines, returning astronauts, paratroopers, and ordinary families—must improvise a resistance against overwhelming odds. As Chinese armor rolls inland and Russian operatives pursue their own agendas, loyalties are tested, betrayals unfold, and the brutal realities of modern asymmetric warfare collide with the deeply human stories of courage, loss, and resilience.

A Dance of Devils is the gripping sequel to Mongol Moon. Author Mark Sibley, a corporate crisis manager and war gamer, delivers authentic tactical detail, geopolitical tension, and character-driven storytelling that will appeal to readers of military thrillers and post-apocalyptic invasion fiction. With its realistic portrayal of great-power conflict, home-front defense, and the extraordinary actions of ordinary people, this novel offers both high-stakes action and emotional depth for fans of contemporary war fiction.
