Finn Kennedy carries a blood curse that drives him mad every 13th of the month, making him violently dangerous. Only the blood or intimacy of a "Maiden of Pure Soul" can ease his suffering and break the curse. Without finding her, Finn faces death by age 30 or falls victim to his half brother Jax's schemes. When Finn meets Lucia Owens, the curse transfers to her. Though this should have been fatal for Lucia, the combination of Finn's daily acts of kindness, their true love, and the birth of their second child finally breaks the curse completely.
