In eleventh-century Byzantium, the empire still appears unshakable. Its ceremonies endure. Its armies stand firm. Its gold coin-the trusted nomisma-passes from hand to hand without question.
Halvard Sigurdsson, a Norse Varangian Guard, believes Rome's strength rests on that gold. When newly minted coins begin to ring duller and yield under pressure, he first defends the empire's integrity-then slowly understands its substance is thinning beneath an unchanged image.
Eirene, an icon gilder who works daily with gold leaf, sees the change before he does. Where Halvard frames it as moral decline, she treats it as material reality-and adapts.
As the empire marches toward the disaster of Manzikert, Halvard must choose: retreat with the living, or stand for an oath whose foundation has weakened.
The Weight of an Oath is a restrained historical novel about loyalty, love, and what remains when the metal beneath meaning grows thin.
