The Bravest Knight Who Ever Lived by Daniel Errico, illustrated by Mo Qovaizi
Cedric grows up a pumpkin farmer, dreaming of one day being a knight. Pretending with friends, he always saves the day, and is offered a flower by the rescued princess. He always kindly declines, just saying that isn't how the story ends.
Through brave adventures, Cedric's dreams come true - he ultimately becomes a knight, bests (but doesn't kill) a dragon, and saves royal siblings, a princess and a prince. And when the rescued princess asks to be his bride, we find out how Cedric's fairy tale truly ends.
