by K. M. Moronova
Once Upon a Demon's Heart centers on the volatile friction between a human protagonist and a demon entity whose worlds should never have collided.

This is not a gentle romance; it is an intense, character-driven journey designed for readers who prefer their fantasy with a dark, psychological edge. If you enjoy stories where the power dynamic is constantly shifting and the chemistry feels as lethal as the magic system itself, this will keep you hooked.
