Society Trilogy Books in Order

The Society Trilogy is the entry point to Natasha Knight and A. Zavarelli’s IVI universe, a secret society built on aristocratic bloodlines, wealth, and rituals that blur the line between devotion and violence. Across Requiem of the Soul, Reparation of Sin, and Resurrection of the Heart, it follows Santiago De La Rosa and Ivy Moreno through an arranged marriage that was never meant to become real love.

Santiago is introduced as a man remade by fire. Scarred in body and mind, he has clawed his way back to power inside The Society with one goal in mind, revenge. Ivy is the seemingly fragile young woman he chooses as his bride, a girl who has grown up on the edges of this world and has no idea what kind of vows she is about to make.

In Requiem of the Soul, Santiago claims Ivy in a marriage arranged to settle old debts and punish those who wronged him. The book lays out the rules of IVI, from its emphasis on noble blood to its often cruel codes of obedience, and it shows Ivy learning quickly that monsters do not hide in the dark. They sit at the head of the table.

Reparation of Sin deepens their connection while everything around them grows more dangerous. Ivy is no longer just a victim or a pawn; she becomes an active force, making choices that complicate Santiago’s plans and challenge his certainty about what he deserves. Outside threats and internal betrayals push them toward a line that neither of them can uncross.

By the time you reach Resurrection of the Heart, the stakes are not just personal but existential. Santiago’s enemies are closing in, Ivy’s past is no longer safely buried, and the secrets of The Society are starting to crack open. The final book pays off the slow build of trust, obsession, and reluctant tenderness that has been there from the first chapter.

Readers can expect brutal rituals, heartfelt moments in unexpected places, and a romance that insists even the most damaged people might still be worthy of a second chance. The Society Trilogy also lays the groundwork for later series like The Rite and The Sacrifice, making it a natural starting point if you want to explore this world in order.
