The Hearth in the Hollow

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.
