Princess Sonora and the Long Sleep
As you can probably guess, this is a Sleeping Beauty story. When the fairies come to give gifts to the young princess, one bestows her with extreme intelligence which leads her to be somewhat reviled by the people around her. Sonora reads everything and has the answers for everything and it causes her to be distinctly separate from everyone. Of course she ends up pricking her finger on a needle and be sent in to a deep sleep for 100 years. During that time the practice of inviting to fairies to christenings ends and a young prince Christopher is born. He is filled with endless curiosity and in response to his questions, he is told "Princess Sonora knows." One day he discovers that Princess Sonora still lives and goes to the castle to awaken her. He does and they make perfect mates as she finally has someone who is grateful for her knowledge and he has someone who will answer all of his questions.
Although not my favorite Biddle story, I really like it. It breaks my heart to see how Sonora and Christopher are isolated due to their respective knowledge and curiosity but then they get to be together and rule justly and fairly.
