After losing his wife and son to a devastating plague, Horace becomes a soldier, sailing to battle for the Great Crusade against Akeshia. A shipwreck lands him on enemy shores, where he finds himself enslaved and on a brutal march across the desert to destinations unknown. When the caravan of slaves encounters a fierce storm, Horace discovers he possesses zoana, a mysterious gift of magic potent enough to instill fear in his captors and to earn him a place in Queen Byleth's court.

Horace quickly learns that life at court is a complex, treacherous prison of its own kind and he remains at the mercy of his foe. With help from Jirom, a gladiator and fellow captive, and Alyra, spy and handmaiden to the Queen, Horace must outwit his enemies and harness his powerful magic to liberate himself and the thousands who have lived in oppression for far too long.

With fast-paced, breathtaking action, magical adventure, and an unforgettable story, Blood and Iron is the stunning first book in the epic Book of the Black Earth series by Jon Sprunk, Compton Crook Award finalist and author of the Shadow Saga.
