Croatia, 1351. Daring knight Gerard Fox and his adventurous wife Willa, fresh from a dangerous quest across Italy and Greece, soon find themselves embroiled in a new intrigue as they sail toward the walled city of Dubrovnik. Having inadvertently hindered a rescue mission, Fox and Willa make amends by helping a desperate Croatian couple forced into a terrible dilemma: either they betray their hometown to a treacherous nobleman and the brutal warlord he serves, or their abducted child will be murdered. A century-old prophecy and a lost codex written by fabled explorer Marco Polo are key to stopping the warlord’s conquest, which could spark a devastating war along the entire Adriatic coast. Fox and Willa race against time to devise a plan for saving a child, a town, and a country, knowing it could cost them everything if they fail.
