The Cursed Crown - Eldritch Heart, #2

In the wake of a twenty-year war, the people of Lucernia struggle to believe their former enemies aren't demon-loving savages. However, that's easy compared to the more alarming change: accepting their nation now has two queens. Many citizens in a land devoted to the God of Purity view the love between Kitlyn and Oona as unnatural, but the young women have earned guarded acceptance in the wake of their heroic deeds.
Alas, unrest stirs in the shadows. Worse, Oona thinks the Talomir family line is cursed. All who have worn the crown before her have met with untimely deaths. Much work lies ahead for the new queens in helping the kingdom recover from a conflict older than its rulers. The people are restless and hurting, trust in the crown is tenuous, and the king of Evermoor demands reparations. That two women should love each other may be the last little piece to hurl the nation into rebellion.
Mysterious forces attacking towns close to the border with Evermoor stoke tensions even further, threatening a relapse to war. Their crowns not even warm, Kitlyn and Oona set off to find the source of the raids and stabilize the nation. hoping to stay ahead of an ancient curse.
