Back to Eternity by Chris Bieniek

This is the story of Ruben, a small town pastor on a mission to evangelize another galaxy, the inhabitants of which have placed science and technology on a pedestal and worshiped it as god. At the heart of the Messier Galaxy is Ocean, a princess in her own right, she embodies the qualities of a woman who knows her identity and her purpose. Stuck in her atheistic society, she dreams there is something more than the dreary perfection that surrounds her.
