Chosen Ones (Lost Souls, Book One)

Life is bleak but uncomplicated for sixteen-year-old Tess, living in a not-too-distant future where the government, faced with humanity's extinction, created the Chosen Ones, artificial beings who are extraordinarily beautiful, unbelievably strong, and unabashedly deadly.
When Tess begins work at Templeton, a Chosen Ones training facility, she meets James, and the attraction is immediate in its intensity, overwhelming in its danger. But there is more to Templeton than Tess ever knew. Can she stand against her oppressors, even if it means giving up the only happiness in her life?
