Everything about Seventeen's life is perfect-from her genetics, to her home in Sanctuary, to her status as a Breeder in the Unified World Order. But all that changes when she meets a rogue Enforcer named Pax who infiltrates Sanctuary and targets her for extraction from the Controlled Repopulation Program. Pax seems to know a little too much about her. He plants dangerous doubts in her mind that accuse Sanctuary of hiding a dark secret, and that cause Seventeen to question everything she's ever known.
When Seventeen's life is threatened, she has little choice but to run away from Sanctuary with Pax. But for Breeders, contact with men is forbidden by law, and even the simple act of taking Pax's hand is treason. Mired in confusion, Seventeen flees with Pax to the outside world and assumes the name Pria, the identity of her childhood. But she is far from certain she's made the right decision when they discover an entire civilization that should no longer exist.
Seventeen, now Pria, is thrust into a position as a key player in a dangerous bid to bring down the Unified World Order. As her world crumbles, Pria must decide who she is and what she really believes. But the truth comes at a cost, and uncovering it will require a greater treason than she could have ever imagined.
