Ten thousand years ago, the goddesses and gods wanted to end the Ice Age. However, first, Otare, a dragon in the ice, must be killed. Eunyau grows up by the sea with her brother Zalon, her cousin Bidyei, and her cousin Vaune, near the Sun Leap Mountains, under the protection of the four giants and other deities. Nevertheless, Eunyau's and Zalon's parents die in a tsunami, and they are raised by Bidyei and Vaune's family. These four children develop very differently. Zalon, since the death of his parents, has a fear of water but is good at climbing. Bidyei becomes a skilled huntress, while her brother Vaune turns into a quiet outsider, acquiring some skills in the process. Over time, Eunyau reveals supernatural abilities that allow her to control the winds and ocean currents. When she turns sixteen, she is chosen to kill the dragon. But then she falls in love with him...
