Before he led Ravka's Second Army, before he created the Fold, and long before he became the Darkling, he was just a lonely boy burdened by an extraordinary power. Eryk and his mother, Lena, have spent their lives on the run. But they will never find a safe haven. They are not only Grisha--they are the deadliest and rarest of their kind. Feared by those who wish to destroy them and hunted by those who would exploit their gifts, they must hide their true abilities wherever they go. But sometimes deadly secrets have a way of revealing themselves...

A prequel to the "Grisha Trilogy" takes the reader into Ravka's mysterious past, when Grisha lived as fugitives and the Darkling took his first steps on the path to power.
