In an eighteenth-century world swallowed by a catastrophic Ice Age, ancient supernatural relics known as Vestigia have been industrialized into brutal instruments of war.
Following the total destruction of his homeland, legendary former British admiral Edward Spencer abandoned the sea to build a fragile, quiet life with his family in snow-buried Marrakesh. But that peace shatters when Queen Isabella of the Castilian Empire summons him back to command. Castilian is suffocating, encircled by hostile fleets, torn by dynastic treason, and on the brink of civil war.
Thrust back into the line of fire, Edward must navigate broadside artillery duels through blizzards and supernatural warfare across collapsing empires. Yet in a frozen world that has forgotten the sun, one question remains: can a man who already lost one nation fight for another without sacrificing the home and family he bled to protect?
