The Awakening (Awakening, Book #1) by KL Hagaman
As their territory is thrown into chaos, princess Lilja and her keeper, a unique guardian by the name of Kaden, must find a resolution and return peace to a people driven by fear. But how does one exactly restore a fallen kingdom if they can't even remember it? After an incident of war, Lilja has found herself just there-lost inside her own mind and a stranger to her very existence. Their destinies entwined, Lilja and Kaden's only hope rests in the hands of a magic wielder whose price for salvation may just be more dangerous than the war itself. Together they must forge a path to save their civilization, but first they will need to come to terms with who they both truly are, because the past is always just around the corner.
