To Rule a Kingdom (en Inglés) - Schumacher

And the Once and Future King shall see the land healed.

With the Treasures of the Gods in their possession, Arthur, Jenyfer and Ordes draw closer to the Grail. A return to Kernou forces Jenyfer to confront the ghosts of her past while Ordes learns the true nature of his magic, as well as his birth. Unsure of her place in the world, Katarin must embrace her history in order to claim her heritage. 

In Dinas Emrys, Lamorna struggles to support Mordred, whose hold on the world of magic is precarious. Surrounded by allies and enemies, she must decide what it truly means to wield power over others. 

Arthur grapples with the dark power of the Sword of the White Dragon, and as his allies gather on Camlann Plain, Mordred calls dark forces to his side, setting the stage for a prophetic battle. 

But before the world can be reborn, someone must make the ultimate sacrifice. 

To Rule a Kingdom is the final book in The Grail Cycle, an epic, romantic fantasy reimagining of Arthurian legend.
