The Last Lighthouse of Asterra

For three hundred years, the magical lighthouse of Asterra has protected ships from the monsters that live beyond the Mist Sea. When seventeen-year-old lighthouse apprentice Elian discovers that the sacred flame is dying, he learns that the lighthouse was never powered by magic alone—it was powered by a promise made between humans and the ancient sea guardians.

Now Elian must sail beyond the forbidden waters with a disgraced knight, a runaway noble girl, and a mysterious boy who claims he can hear the ocean speaking.

If they fail, the Mist Sea will swallow every coastal kingdom.
