The Dragon King's Double Stand-In

After my brother ran from his wedding, my father forced me to take his place and marry the feared Obsidian Dragon King. Everyone knew I was the useless son of the Starborn—eighteen and still unable to awaken my power. But on our wedding night, his touch awakened a royal bloodline believed extinct for a century. I thought that finally made me worth something. Then he put a collar around my neck and forced me to become his lover who died ten years ago. That’s when I realized— I wasn’t just replacing my brother. I was replacing a dead man, too.
