Sister's Keeper

Alia, a highly respected peace control officer among an alien species called the Quasarians, is the first human to hold the title. Kendra, a human terrorist rebelling against the invading alien species, is now in jail, accused of a suspected bioterrorist attack. These two women are sisters, meeting each other for the first time in years. Alia holds her younger sister’s fate in her hands. Or is it the other way around?
