Joe and Alex's love was once unshakable—until a rescue mission left Joe broken and convinced Alex was gone. As Joe spirals into the shadows of his own mind, Alex fights to reach him, desperate to restore the bond they once shared.

The holiday season brings flickers of hope, and with it, an unthinkable shock: Joe's parents, long presumed dead, return. But they are changed—distant, cold, and unwilling to accept Joe's life with Alex and their twin sons. As the family reels from their reappearance, Joe and Alex face a painful choice: allow them back in, but strip them of their power within the family to protect what they've built.

Then, tragedy strikes again. An airplane crash destroys their home at Jonders Cove, forcing the family to rebuild from the ground up. In the aftermath, Nicky enters their lives as the designer hired to restore Joe and Alex's apartment. But her presence stirs something deeper—Joe's silent shock at hearing her name reveals a buried truth: Nicky was the first person he ever shared himself with, and his parents did everything they could to keep them apart.

As Nicky unveils the full extent of their manipulation—and the lives they damaged in the name of control—Joe and Alex must confront the legacy of cruelty that shaped their past. Together, they forge a new bond with Nicky, uncovering long-buried secrets, ancient family power, and a trail of wealth and relics that threaten to pull Joe back into darkness.

Unbroken Vows is a story of survival, reckoning, and the fight to protect love against the weight of betrayal. As Joe battles ghosts both real and imagined, he must decide whether healing is possible—or if some vows are destined to break.
