Acropolis 3000

Trinity Academy is the only school in the city-state of Acropolis to accept three classifications of humans as students-the elite C-1s born of natural birth, C-2 replicons grown in tanks, and C-3 clones. Students attend four terms to prepare for a lifelong service in the Acropolis Army-AirCorps. In the Frontier live REMs, registered mutants created by the nuclear fallout after WWIII, and it's the AAA's job to protect and serve until death.
For Demetri, a shy and awkward C-2, the academy offers the only opportunity to hone her fighting skills and learn proper social behaviors within a competitive environment where "pain is the best teacher." However, Demetri soon discovers something is wrong with her and her fellow replicons. Designed to be passive, celibate intellectuals, she and her classmates display a strange feral appetite for violence and intimacy.
When students start to disappear overnight mysteriously, Demetri sets out to discover the truth about her creation and the world, placing her siblings and friends in jeopardy, for those who question authority do not live long.
