My Alpha Loves My Sister

When alchemist Isla discovers she carries the last traces of the legendary Moon Goddess bloodline, her quiet life of research and solitude shatters forever. Forced into a blood bond with Alpha Rowan—a man whose heart belongs to her sister—Isla becomes a pawn in ancient werewolf politics she never wanted to join.
But as hunters close in on their secret and forbidden feelings bloom in the shadows of duty, Isla must choose between the freedom she's always craved and a love that could either save or destroy them all.
