Book two of the Heartspire Trilogy.

Peace was only the first battle. 

With the Heartspire stabilized, Calypso and Atreus are the living bridge between Seelie light and Unseelie shadow—adored by the Convergence and feared by two uneasy courts. Power makes enemies. A Seelie coup fractures the sunlit court. An Unseelie usurper raises a rebel army. And from legend steps a relic with a single purpose: the Crown of Dawn and Dusk, forged to control unity magic—or end it. 

Dragged home by duty and hunted by zealots, Calypso must face the kingdom that once caged her. Imprisoned “for his safety,” Atreus must defy the throne he was born to serve. When a vision shows one crowned and the other erased, love becomes a weapon every faction wants to wield. 

To stop a war and keep their bond from becoming a cage, the heirs of flame and frost must refuse the roles written for them and bind the Crown not to a person, but to the land itself—even if it costs them the very magic that made them legends. 

Political romantasy, knife‑edge stakes, and a love that chooses partnership over prophecy.
