When a tragic accident claims the lives of her parents, young Princess Cécilia ascends to a throne overshadowed by turmoil. Under the watchful eye of her uncle, who serves as regent, her kingdom begins to fracture. Whispers of betrayal, oppression, and unrest grow louder, but the true orchestrator of the chaos remains hidden in the shadows.
After narrowly surviving an assassination attempt, Cécilia is forced into hiding, accompanied by the mysterious and battle-hardened mercenary Kassian Arthur. Together, they traverse the far reaches of the Northern Isles, encountering her people's anguish and learning of an oppressive regime bent on crushing dissent. As her kingdom teeters on the edge of war with the Renuso Empire, Cécilia must find allies in unexpected places and rally those who still believe in her.
But the enemy is cunning, their identity cloaked in secrecy. Every step Cécilia takes reveals more layers of a conspiracy that has haunted her family for years. As war erupts, she must summon the strength to lead, even while grappling with her own doubts, loss, and growing feelings for Kassian.
With bloodshed threatening to destroy everything she holds dear, Cécilia risks everything to confront the truth. The journey to reclaim her throne will test her in ways she never imagined-but in the end, the most dangerous enemy may be the one she never saw coming.
