My name is Amberly, and everything I've ever been told is not true. Monsters don't exist. False. The nightmare spectral world is just my imagination. Lie. In a few months I will finally be free. False. I realized this when I entered the secret training academy. I was kidnapped by unusual creatures - children of fallen angels who call themselves Nephilim. They say I'm one of them. But every day I feel more and more the difference between us. The Nephilim believe that I will become the death of everyone. Perhaps they are right. Because the monsters have already found me. And now they are trying to break through the walls of the academy. The salvation of loved ones is only in my hands. And I must escape from this kingdom of monsters once and for all.
