A Crown Between Shadows is a dark romantasy about Belle, a mortal thief who steals what she believes is a valuable relic, only to discover it is a realm-crossing key tied to ancient fae power. When she accidentally activates it, she is dragged into a dangerous fae kingdom ruled by ruthless politics, lethal magic, and a crown that demands blood. Thrown into a world she does not understand, Belle becomes entangled with two powerful fae twins. Donovan is the exile who once lived in the mortal realm at her side, and Davion is the cold heir who sees her as a threat, a curiosity, and a prize he has no intention of losing. As war brews between realms and long-dormant magic stirs inside her, Belle must navigate deadly court intrigue, violent loyalties, and a bond she never asked for. Hunted, underestimated, and rapidly awakening to a power she does not fully control, Belle must decide whether she will bow to a kingdom that wants to break her or rise to claim a fate that terrifies even the fae themselves. Perfect for readers of Rebecca Yarros and Callie Hart, this story blends brutal fae politics, morally gray romance, slow-burn obsession, and a heroine who refuses to be tamed or silenced.
