Nobody's Quest by Alyssa Day

For a hundred years, Altarra has burned. Corvynne, the goddess of war, has conquered kingdom after kingdom, leaving only ruin in her wake. Every prophecy says the same thing—nobody can defeat her.

And after a century of failure, someone finally takes that literally.

When the goddess Artemisen chooses Soli Graymind—a young woman who has spent her life believing she doesn’t matter—to lead one last, desperate quest, the world laughs. But Soli won't be alone. She's joined by an unlikely group of companions, all of whom harbor deadly secrets:

A prince determined to win back his kingdom.
A thief with a plan to go his own way.
A sorcerer whose magic is unreliable.
A warrior with a hidden agenda.
A noble with a mysterious past.
And two soldiers whose loyalty to a tyrant king may outweigh their dedication to the quest.

Together, they are Altarra’s last chance.

And if they have any chance to succeed, they need to believe that being a "nobody" is more powerful than anyone imagines—including themselves.
