Renegades
"The Renegades are a syndicate of prodigies--humans with extraordinary abilities--who emerged from the ruins of a crumbled society and established peace and order where chaos reigned. As champions of justice, they remain a symbol of hope and courage to everyone--except the villains they once overthrew. Nova has a reason to hate the Renegades, and she is on a mission for vengeance. As she gets closer to her target, she meets Adrian, a Renegade boy who believes in justice"--Amazon.com.
