They survived the clones. They survived the betrayals. But can the Unity survive the truth about what Aria really is? Aria Winters thought defeating her evil clone was the end of the Shadow Council's schemes. She was wrong. Three weeks after the facility's destruction, the nightmares start. Every time Aria touches the Void, it whispers to her. Calls to her. Feels like home-and that terrifies her more than any battle ever could. Because the Twelfth was right. The Fifth bloodline isn't just connected to the Void. According to ancient texts, Aria's ancestors came from it-the first beings to crawl out of the spaces between spaces and take human form. She's not a mage with Void powers. She's a creature of absence wearing human skin. And the Shadow Council knows exactly how to use that against her. When the Council sends visions designed to make Aria doubt herself, doubt her control, doubt whether she's even human anymore, the Unity bond becomes her only anchor. Dante's fire keeps her warm. Kade's shadows keep her grounded. Ryder's chaos keeps her laughing. Thorne's darkness proves she's not alone in her fears. Together, they're unbreakable. Apart, they're vulnerable. And the Shadow Council's new plan requires them separated. With only eleven weeks until Winter Solstice-when the dimensional barriers are thinnest and the Void hungers most-Aria must master the very power that threatens to consume her. She must learn to control the nothing. Command the absence. Become the living seal her ancestor created two thousand years ago. But mastery requires touching the Void. And every time she does, she loses a little more of her humanity. Four sexy-as-sin heirs who would burn the world for her. One ancient prophecy that says she'll end it. And a bond that might be the only thing standing between reality and the abyss. The Shadow Council is coming for the seal. They're coming for Aria. And this time, they're not trying to break her from the outside. They're going to make her break herself.
