The Young Elites By Marie Lu

Adelina Amouteru is a survivor of the blood fever, marked by a jagged scar where her left eye once was. Branded as malfetto - an abomination - she is cast out from all she has ever known and loved. Adelina finds sanctuary with other malfettos and discovers that the disease has left her with more than just a scar - she has a mysterieous and powerful gift. She is a Young Elite. But Adelina's ability is stronger than any Young Elite before her. And unless she can control the vengeful darkness growing in her heart Adelina could be a danger to them all.
