Quiet, soft-spoken she-wolf Elara’s world tilts violently off its axis when her single mother marries the ruthless, widely feared alpha heir of the region’s most powerful werewolf pack. Her new stepbrother Kael is the legendary figure every shifter whispers about: unyielding, fiercely protective of his people, and strictly off-limits, barred by ancient unbreakable pack law that forbids any romantic bond between newly related step-siblings. No one suspects Kael has hidden his all-consuming, long-buried obsession with Elara for years — even long before their parents ever crossed paths. When a vicious rival pack targets Elara to strike at Kael’s lineage, he shocks the entire shifter community by claiming her as his fated mate out of nowhere, ready to throw away his entire birthright and face permanent exile from his own pack just to keep her safe.
