Heaven wants her captured. Hell wants her dead. And time is running out.

Aurelia's worst fear has become reality—she's been officially branded a traitor by Heaven itself. Accused of causing the demonic surge on Earth, she now faces the wrath of archangelic enforcers dispatched with a single command: bring her in or take her out.

With nowhere left to turn, Aurelia and Cassian become fugitives, relying on a fragile network of sympathetic angels and hidden safe houses. Each step closer to the truth forces them deeper into the shadows as they assume false identities and stay one step ahead of heavenly justice. But running isn't enough—Aurelia needs proof of the real traitor's alliance with the demon lord Sarathiel.

The evidence exists, locked away in celestial archives beyond her reach. Her only hope lies in infiltrating a hidden "terminal" on Earth—an ancient gateway into Heaven's knowledge that could reveal the conspiracy threatening both realms. The risk is catastrophic; the reward might be the only thing that could clear her name.

Meanwhile, Sarathiel seizes the chaos as his opportunity. With Heaven's forces fixated on hunting Aurelia, the demon lord's minions emerge into daylight, wreaking havoc across major cities and claiming territory once protected by guardian angels. Each day, the mortal realm slides closer to infernal dominion.

For Cassian, everything he's ever believed faces its ultimate test. The oath he swore to Heaven demands Aurelia's capture, but his heart demands her protection. When he irrevocably chooses her side, sacrificing his standing among his angelic brethren, their connection transcends mere alliance. In the crucible of danger and desperation, their bond becomes an unbreakable fusion of souls—a source of power neither expected but both desperately need.

When Aurelia finally uncovers irrefutable evidence revealing the traitor's identity and their catastrophic plans to merge Hell and Earth, the stakes escalate beyond imagination. The fate of two realms now rests in the hands of those both realms have rejected.

In a war between Heaven and Hell, sometimes the only path to salvation lies in betraying everything you once held sacred.
