Lena was an ordinary girl. I ran in the morning, went to classes at the institute, and worked part-time in a restaurant. True, it was difficult to find friends. It's all because of her incredible gray eyes. If people looked at them for too long, fear shrouded their hearts. But one day a girl saved a cat from teenagers, not even knowing what her nobility would lead to. After all, this cat will very soon want to see her again. And Lena herself will very soon have to learn about a dead civilization and about its most terrible enemy. About an enemy who lost the battle, but is ready to take revenge. And now the girl has to learn about her new role and make a choice. A choice on which not only her life depends, but also the lives of everyone around her. And among them there will be not only strangers...
