Haunted Hearts (The Bound Duet #2)

The haunting has only just begun.

Cade Halloway is done running. The Covenant still stands—fractured, desperate, and willing to burn the world to reclaim their power. They still want his sister, Callisto, but Callisto is no longer the girl they marked for death. She trains in secret, learning to wield the power she was born with. And the rules begin to change. With the help of an old friend, a monster forced into human skin, and you—the unseen presence bound to Cade—they prepare for the war coming to their door.

As Cade moves to finally dismantle the Covenant, his connection to you deepens into something he no longer questions. You are no longer a ghost, you are a part of him now. And he intends to find you. But while alliances take shape, something else watches from the shadows. Waiting for every piece to fall into place.

This time, survival won’t be enough.
