Dragon King Charlie: The Dragon Mage Book 3

Charlie thought being king would be easy after building a spaceship, but ruling is proving harder than expected. He's now king of a realm where people mostly respect (or fear) him, especially with a giant dragon guarding him.

Things seem to be going well, but Charlie fears it won't last. A mysterious new threat emerges, one that may even possess magic—an impossibility on this world. Yet, impossible things tend to happen to Charlie.

Now, facing an unseen enemy, King Charlie must protect both his friends and his subjects. This spaceman from Earth hopes he's up to the challenge ahead. Can he balance his duties as king while fending off this mysterious opponent?
