Used book – Vega Child of the Night, Sarah Cohen-Scali

The child was completely naked, her skin black with grime. Her hair was her only clothing. Long, abundant hair that was now nothing more than a tangle of knots, matted with saliva and food debris. A shapeless mass that hid her face... "The guild agents brought her to us this morning," the professor told Agena. "She attacked several passers-by. We'll call her Vega. You'll be exclusively responsible for her!" This is how Agena, recently arrived at the Fomalhaut center, was entrusted with this delicate mission which quickly transformed into an incredible and supernatural story. Who is Vega? What is the professor looking for?
