The Dragon Fae King by Clara Hartley

I want to be left alone.
But the fae king only knows loneliness.
And he needs me to save him from it.
Neremin Eilreine, the dragon fae king of Cardell, has lived almost one-hundred years without a fateful companion. He serves his duty well, but he doesn’t have anybody to understand him. He believes he can’t find someone like that, although it’s his heart’s deepest longing.
A foretelling from a special orb draws Neremin to the dryad forest. He needs to subdue the undead coming alive from a range of mountains. During his travels, Neremin mysteriously loses his magic—the one thing that makes him revered. He finds himself trapped with Alyxe Bellquaine, a dragon fae recluse who has been in hiding for the last twenty-five years.
Alyxe draws him with her strength and straightforward attitude. She’s capable, having built a life in the dryad forest all alone.
But Alyxe won’t return with him to the dragon fae homeland. She wants nothing to do with it. An accident twenty-five years ago resulted in her killing all her friends.
Alyxe would rather die than face the consequences of her actions.
But Neremin will not let himself be separated from her.
