Black straits. Iron fires.
Northern shields. Gold before fire.

At the Bosphorus, Torfi Thorstein discovers that the greatest city in the world does not need an army to break a man. Constantinople has dues, registers, false seals, and men who can turn a name into a debt before its owner reaches the quay.

With Dagr beside him and Zoe watching the imperial records, Torfi must hold his company together through burning warehouses, shadow ships, corrupt officials, and a war fought with paper as often as steel.

But when fire comes to the water, every oath, every rescue, and every piece of silver becomes a weapon. To survive, Torfi must prove that northern shields can serve the Empire without becoming the property of its hidden masters.

Fire on the Bosphorus is the seventh volume of The Viking Blood Saga, a dark historical adventure of Norse warriors, Byzantine intrigue, naval combat, and the brutal price of power.
