Blood pools beneath the High King's corpse as his own brother clutches the fatal dagger, still warm with betrayal. In ancient Ireland, where oaths were sacred and kinship divine, Ugaine Mor's murder unleashes a tale of passionate love, horrific brutality, savage vengeance, and the terrible price of breaking an unbreakable vow. Some debts can only be paid in fire & blood.
