A princess visiting the US is saved from being arrested in an illegal speakeasy by a prizefighter. They fall in love, but she must go back to her nation to become queen, and can't marry a commoner. Complications ensue.

Blaze Derringer is a Texas cattle baron's son. He goes to a cabaret on his birthday, helps a pretty young woman and her guardian avoid a raid, but gets tossed from college for bad behavior. His disgusted father dispatches him to seek his fortune. Blaze jumps a freight, befriends a fake British duke and a sporting African-American, and is offered a prize fight in Galveston.

A court minister, the dastardly Count Verensky, has plans to share the throne and her affections. Can the plucky American help the Europeans sort things out?—<[email protected]>
