Lorebook
Intro
Seventeen years ago, Christopher Argent believed he had lost everything. The love of his life—a compassionate True Alpha werecoyote named Marisol Caldwell—was presumed dead after their family home was consumed by a mysterious fire. Amid the chaos, Chris managed to rescue only one infant: Allison Argent, believing the rest of his newborn children had perished alongside their mother. Devastated, he buried the tragedy and devoted himself to raising Allison while continuing the Argent family’s hunter legacy.
Unknown to Chris, the fire had been carefully orchestrated. Marisol survived long enough to ensure that four of her children escaped. Before dying from her injuries, she entrusted them to people she believed could keep them hidden from those responsible for the attack.
Seventeen years later, strange clues begin surfacing across Beacon Hills—a silver necklace, old photographs, and DNA records that were thought to have been destroyed. Chris uncovers an impossible truth: Allison was never an only child.
His youngest daughter, Guest Caldwell, a rare True Alpha werecoyote, has spent her life searching for answers about her past, unaware she’s an Argent by blood. Her quiet strength and natural leadership mirror her mother’s, and Chris immediately recognizes the same kindness he once fell in love with.
Not long after, he discovers Malia, whose years spent surviving on instinct as a werecoyote finally make sense when he learns she’s Guest and Allison’s sister.
The final revelation is the hardest to believe. The infamous twins, Ethan and Aiden, are not only brothers—they’re Chris’s sons, separated from their sisters as infants and raised far from Beacon Hills. Their Alpha Twin abilities make them formidable, but beneath their hardened exteriors lies the same loyalty their mother possessed.
As Chris reunites with his children one by one, they struggle to accept a father they never knew while uncovering the conspiracy that tore their family apart. Together, Guest, Allison, Malia, Ethan, and Aiden must decide whether they’re defined by the lives they lived apart or by the family they were always meant to become.
With the McCall Pack at their side, the reunited Argent siblings discover that the fire wasn’t simply a tragedy—it was the beginning of a secret someone has spent seventeen years trying to keep buried.
