Rejected by A Fake, Worshipped by Three Queens

A boy was burned alive to save three girls. Eighteen years later, they became a queen, a governor, and a bard--and slew the dragon, only to learn he survived. Now a nameless tavern drudge, he faces execution for his fiancee. At the final stroke, the three women burst in and knelt. Divine power awakened. He was the High Priest of the Pantheon.
