Their marriage united two kingdoms. Their love imprisoned an ancient evil. But their enemies know exactly how to break them.

Weeks after ending a fifty-year war, Queen Liora and King Callum's fragile alliance faces its greatest test. When urgent research forces them apart, coordinated poisonings strike both monarchs on the same night. Callum fights for his life in Valdris. Liora fights for her life and that of their unborn child in Glenmara.

And the unified crown—the magical seal keeping the Shadow King imprisoned—fractures.

As they hunt fifteen conspirators scattered across both kingdoms, a darker truth emerges: the mastermind isn't a disgruntled noble seeking power. He's Kaelith, a fallen mage who has served the Shadow King for five hundred years.

The assassination was never about killing them. It was about breaking them.

Every loss weakens the seal. Every moment of grief feeds the darkness. Every crack in their marriage brings the Shadow King closer to freedom. And Kaelith's final ritual—timed to a lunar eclipse—will shatter the prison entirely.

To stop him, Liora and Callum must assault his fortress in the frozen north, repair their fractured bond, and face the truth: saving their kingdoms will cost three heroes their lives.

The crown is broken. The seal is failing. The Shadow King is waiting.
