Amelia grew up in a world of half-truths. She knows she's an Elder but has no idea what that means. Her father reminds her daily that she must maintain control but he refuses to explain why. Even worse, she's betrothed to the prince of the Immortals and she doesn't even know his name. Finally breaking free to live a few normal years at a community college, the last thing Amelia expects is to find her best friend in a cheeky Southern girl and to fall for a self-assured human who sees her for who she is and not what she'll be. As she learns more about herself, Amelia realizes the line between love and duty is a thin one. As her power continues to increase exponentially and her questions are slowly answered, Amelia must make the ultimate choice. The question is, will her head or her heart win the battle?

Aidan Montgomery hadn’t been prepared for Amelia Bradbury to walk in and then out of his life. He also hadn’t expected to find the powerful magic hidden deep within him for the last nineteen years, but he’s embracing it—finding more control and more answers every day. Now, with the help of Amelia’s best friend, Bethany, Aidan is on a quest to understand his destiny and find Amelia. Amelia decided to stand by her duty, which meant walking away from her first chance at love. Trapped in Cresthaven at the Queen’s mercy, she spends her days with Micah—an ally she still holds at arm’s length—struggling to manage her heartbreak while keeping her mind focused on the task at hand. As she continues to unlock the secrets of the Keeper power, Queen Julia’s true motives reveal themselves, forcing Amelia to decide, yet again, how much she’s willing to sacrifice. Will Aidan get to Amelia before it's too late, or will the very power that sustains them keep them apart?

Amelia Bradbury is finally free from Queen Julia and Cresthaven, but she isn’t safe yet. The Keeper power runs rampant inside her and it will take an ultimate act of selflessness to contain the darkness that threatens Amelia’s sanity and the future of the Immortal race. Aidan Montgomery refuses to give up on Amelia. Once she’s rescued from the Keeper’s hold, he intends to prove his love is more than a side effect of the prophecy, even if doing so leads him away from his pack and on a journey that will irrevocably change them both. When the past and the present collide and the shocking origin of the Immortals is revealed, Amelia and Aidan are forced back to Cresthaven to end a war that never should have started.
