Unwanted

All her life, eighteen-year-old Bea has wanted nothing more than to become a sniper on the wall and earn the coveted ink of a Dread warrior - a mark of distinction among her people. She knows that one day the terrifying Erebii might break through the city's outer defences, and if her people aren't prepared and the wall is breached then the last human city will fall. But everything Bea thinks she knows is about to be challenged... What does the ink really do as it flows underneath their skin and who is the mysterious Unwanted boy that keeps appearing in her life?
