Fiamma, once human, now a hybrid Scourge, is trapped in a velvet cage-her beautiful voice twisted into a weapon. Desperate for freedom, she reaches out to Elysium, a battle-scarred assassin of the OneCreator with his own haunted past. As rebellion ignites across OneWorld, Ely must decide if Fia is a threat or the key to his happiness. Together, they uncover secrets, face deadly foes, and forge a bond that could change them forever. But as war looms and old powers stir, their love may not be enough to save them and OneWorld.
