The Echelon. The Echelon

On an Earth ravaged by toxic waste and violent mutants, one girl with power in her blood will rise to save them. Only the Decemites-carefully selected children injected with nanobots and trained to survive the treacherous terrain Earth has become-can survive the outside long enough to collect resources for the domed city of Echelon. Decemites who serve long enough have a chance at a better life. But few live to experience their reward.
Myla's only ever known the stratified life inside the dome. As the secret child of a forbidden Decemite relationship, she has abilities like no one else, abilities she's had to keep hidden her entire life. But when her Decemite sister goes missing on a mission, Myla's search to bring her home will uncover the truth about the Outside and the secrets the leader of Echelon has been keeping. No normal human is supposed to be able to survive outside the dome, but rebel Outsiders prove that wrong.
By her side is Lock, the Decemite golden boy and unlikely companion in her quest. As she grows closer to Lock, a rebel boy, Ben, shows her the lies that Echelon has been keeping. He draws her deep into the rebel world and a life she never could have imagined. As she uncovers the ugly truths about Echelon, Myla will have to make a choice: can she ever go back to her old life, or is her only chance at freedom to tear down the only world she's ever known?
