Dueling the Suitors by Karen Daliath

What if the princess unknowingly said “I do” to the very enemy threatening her kingdom?
Princess Astoria always hated the idea of marriage.
So when her father demands she wed a powerful wizard to defend their kingdom from invasion, Astoria agrees on one condition: her prospective groom must first defeat her in a magical duel and prove himself worthy of her hand.
Suitor after suitor, Astoria bests every magic-born man her father presents, earning her fame across the continent as the Unyielding Princess of Daliston.
When no mages remain to challenge her, a lowly street performer arrives at the castle to face the renowned princess. Little does she know, this mysterious stranger may be the only one powerful enough to defeat her in the duel.

But what happens when her champion turns out to be the one man she never expected?
