Lord of Destiny

In the city of Karthos, the bells only ring at midnight for one reason: the Weaver has chosen a new Lord of Destiny. Kael Veyr is a scribe’s apprentice with nothing to his name but debt and tired hands. He was never meant to be chosen. Now a black thread is fused to his wrist. It lets him see every life, every choice, every fate. Pull one thread and a king dies. Cut another and a child is born. But power has a price. With each choice, the mark creeps closer to his heart. And when it reaches it, Kael will stop being the one who holds destiny... and become part of it. The last Lord of Destiny is dead. The next one is going mad. And someone is pulling the threads of the world apart on purpose. To save Karthos, Kael will have to decide who pays. — Description from novelcodex.org
