Elina and the guardians grow stronger, but enemies aren’t sleeping either. They invent new ways to detect the Spark. And now, within the walls of the academy, a new net is being woven to catch the girl. Somewhere far away at the other end of the world, the dark god Cain isn’t planning to give up—because once Sparky was in his embrace, she became even more necessary to him. He still doesn’t know that the girl’s heart has long been given to someone else, so he can’t even imagine the possibility of rejection.
