A Kingdom of Ruin by K.F. Breene
Never sell your soul to the Demon King. Too late. In an effort to save all that I love, I have to finish the job Nyfain started… and ruin myself. I’ve made a trade with the most cunning creature alive. Me for them. The dungeons will be my new home. Dolion’s destruction will be my new goal. I just have to get out of here and back to my golden dragon. Preferably alive.
