The Hearth in the Hollow (en Inglés) - Alastair Finch

The assassin was sent to kill a monster.

Instead, she found the only man who could save the world.

Lyra Ashworth carries a hidden blade and a deadly secret. Sent to infiltrate the fortress of the infamous Void-King, her mission is simple: gain his trust and end his life.

But Malakor Vayne is not the tyrant she expected.

He is the last shield against a living fog that devours kingdoms-and the darkness in his blood is the only thing keeping it at bay.

When a powerful magic binds their souls together, assassin and king must fight side-by-side against the ancient power that created the fog itself.

Because if Malakor falls...

The world falls with him.
