La segunda muerte de Locke

Grey Flynn has dedicated his life to his mage, Kier. She will be his sword, his healer, and his protector on the battlefield. The deep well of pure magic within him exists solely to serve him. Grey would do anything for him, be whatever he asked, if only he would ask. When the mission to protect the daughter of an enemy kingdom draws them into the heart of war, Grey and Kier must decide what they are willing to sacrifice to keep their secret safe. Because Grey is not just a magic well, and if she dies, all the magic will disappear with her.
