On the night Sienna Carter discovers that billionaire Alpha Adrian Blackwood is her fated mate, she expects him to claim her. Instead, he rejects her in front of the entire pack. "You are not fit to stand beside me.” Humiliated and heartbroken, Sienna leaves Silverpine believing she has lost everything. But the rejection awakens something inside her. Something ancient. Sienna isn't an ordinary wolf. She is the last descendant of the First Luna, a bloodline thought to have disappeared decades ago. And Adrian knows more about her identity than he is willing to admit. Two years later, Sienna returns to Silverpine as a completely different woman. She's no longer the powerless girl he rejected. And Adrian discovers the terrible truth: The woman he rejected is the only person who can save his pack-or destroy it. Something the pack leaders have spent generations trying to find.
