Divine Children

An aging star ship captain dies, leaving his massive vessel on a collision course with a nearby planet. Meanwhile, an unexpected object appears in the night sky. Ernst, a 19-year-old orphan in a primitive utopian dwelling tribe, offers to seek out council from the wizards across the sea. His people think he’s crazy to even attempt such a dangerous journey, but he gains confidence when Enna, his unpredictable wild-haired friend joins the adventure.
Along the way he discovers that he possesses mysterious unexplained powers. Ernst and Enna must find a way to stop the late star ship captain’s tyrannical successor, Huxley Bradford, before he intentionally destroys Ernst's entire race in a methodical act of genocide. The story takes a turn for the unexpected when these young heroes discover a forgotten secret about the world they thought they knew.
Ernst will either be broken by the journey or molded into the leaders he must be in order to save his people. Enter a rich world of colorful characters, layers of mystery, and powerful ideas.
