The moment Ari Bowers stepped inside the abandoned farmhouse on the outskirts of White Haven, Pennsylvania, she wanted to hightail it out of there like the ghost-fearing girl she was. Instead, she let her crush, Marcus Wagner, lead her into the shadows. Oops. As she predicted, they ran out screaming. But something followed her home. Since that night, Ari is haunted by something she can't see. It watches her when she sleeps. It caresses her in the shower. It carves words into her skin and lives alongside her, never satisfied with her terror. It always wants more, and Ari begins to fear it will take her and her date back to the farmhouse forever. For Ari and Marcus, it's not a matter of whether or not monsters are real; it's a life-or-death race to figure out which one is out to drag their souls to hell.

The final chapter in the war for Ourea ends with blood. Kara Magari is an icon. A hero. The people love her. The royalty tolerates her. She has everything - an army, allies, and a close circle of chosen family. They believe she will end the war, and they shouldn't. She's as scared as they are. She just can't show it. The war she accidentally started ends with a final battle that will either save or enslave her people. She will do anything to win - until she learns the cost of victory. Braeden Drakonin is afraid of what he'll become when he takes over his father's kingdom - that much authority can change a man. But his father has already tried to kill him more than once, and it's time to end his reign. Braeden's armies are ready. His strategy is foolproof. His generals are waiting for the order to attack. It's only in the final seconds before the battle begins that he realizes he missed one crucial detail - the traitor.
