In 1742, young Daniel Lind goes to Russia to the shores of the Kara Sea and there finds another descendant of the People of Ice Shira, the daughter of Wendell Grip. As the family legend says, the young people’s ancestor, Tengel the Evil, may one day wake up and destroy his descendants—along with the whole world. The gods told Shira about two sources on the mountain of four winds: the source of evil, from which Tengel the Evil drank, and the source of good, which can only be reached by a spirit pure of heart. To stand against Tengel the Evil, the chosen one from the People of Ice must find the sources. Shira and Daniel set off on a dangerous journey.
