Bound to My Enemy Dragon King

Queen Maeve and Malakor want an ancient power, and getting it takes the immortal light of the fae heir and the heart of the dragon king. The hundred-year war between the fae and the dragons is their doing. The fae heir is Crown Princess Elara Valenne, and her coronation is coming up. Beyond the border she finds a man dying and saves him. He is Kael Varyn, the exiled Dragon King, the enemy her kingdom swore to destroy. Saving him wakes an old bond that ties her senses to his body. She feels his wounds and hears his heartbeat, and what he wants she wants too. If he dies she will die with him. She hides him as her personal guard, which is treason, while she looks for a way to undo the bond. What she finds instead is who has been running the war and why. Maeve and Malakor intend to sacrifice both heirs, and one of the two has already been chosen. Elara and Kael have to decide whether to break the bond or keep it.
