Embers of the Underworld

She can pull souls from the dying. He rules the dead. Neither of them expected to need the other. Seraphina has one gift and one curse: she can reach into a dying body and take what the Underworld has already claimed. She uses it quietly, carefully, and never for herself. Until the night she pulls a soul that was never meant to leave-and the Lord of the Underworld comes to collect it personally. Kaelan has ruled the realm of the dead for centuries.
Nothing surprises him. Nothing moves him. No mortal has ever looked him in the eye without flinching-until Seraphina, who did not flinch, and did not apologize, and somehow took something from him far harder to retrieve than a misplaced soul. To fix what she broke, they must work together. To work together, they must enter the Underworld side by side. And somewhere in the dark between the living world and the dead, the rules Kaelan has kept for centuries begin to feel less like law and more like something he could choose to break.
A dark romantasy of stolen souls, reluctant gods, and the ember of something neither of them was supposed to feel.
