Sylvaine Lygwon, a Margrave’s daughter of unmatched beauty and pride, is forced by royal decree to marry her first love, Aster Dilseon. But the reunion is a nightmare: Aster has become a cold-hearted man who openly keeps a mistress, Aura, within his estate.

Abused by servants and stripped of her dignity, Sylvaine vows revenge. She soon uncovers a scandalous secret. Aura is actually a man in disguise. Leveraging this truth, she forces him into a partnership to bring Aster down.

As they navigate their shared deception, their cold alliance shifts into a dangerous, soul-stirring attraction. When Sylvaine is pushed to the brink of death, Aura makes a desperate choice to save her: he sinks his fangs into her neck, binding them forever through a vampire’s blood pact.
