Asher

2147. A century since the Vanishing first occurred. Some thought is was a plague, others a change caused by the sun, or different air molecules. They believed it entirely harmless. A discoloration to the iris of the human eye. Something so simple sometimes it could be missed entirely. Little did they know the dangers that followed.
Continent after continent, humans started Vanishing. A bright light, and suddenly they disappeared. No body. No blood. No nothing. All trace of their physical being, gone. The number of Vanishings increased swiftly, sweeping the globe until it left mere millions. Earth nearly empty of humanity. A world with only shadows of what had thrived there. Almost nobody left to wonder where everyone had gone.

Residing deep within the depths of the Sahara Desert, is Carcere Prison. An female-youth research facility for criminals and Ashers; people in the beginning stages of the Vanishing. For Tessa Scott and the other inmates, the powerful walls of Carcere hold much more than concrete.
In the midst of experimentation and the powers that be, can Tessa find within herself the strength to survive? Can she face the truths that could hold the key to the Vanishing? Or will humankind perish, once and for all?
