Academy 505. Cycles of Remali

After a year in a psychiatric hospital, my brother and I were sent to Academy 505 — where people with awakened superpowers after the catastrophe are trained. Against our will, we must undergo training and become instruments of murder to protect the surviving world. However, Kai Alcaster intrudes into my life — the son of the ruler, with cold eyes and a desire to destroy me. Forbidden feelings flare up between us, which neither of us can resist.
Who is behind the events of four years ago? What connects Kai and the teacher who can't take her eyes off my brother? And why do I feel like we've met somewhere before?
