"A Wrinkle in Time" is our all time favorite, and "The Little Prince" too!
The Little Prince was always a favorite of my brother and me, and so was
Jonathan Livingston Seagull.
Stories and myths, all have esoteric meanings, and i find it very interesting how the storyline changes according to culture and geography of the people.
I saw
Little Red Cap being mentioned, and recently i heard a story from Central/Eastern Europe (might have been Poland, not sure) where the story's ending is quite different than the mainstream one. There is no hunter at the end to kill the wolf, and once the grandma is eaten, well... she's gone for good. But when the wolf lies in bed dressed as grandma, and convinces the little Red Cap to lie in bed with him, the girl begins to observe how different his features are from those of an old woman. She asks questions, to verify her uneasy feelings, and the wolf's answers make her all the more worried. At a moment of courage, and after some thought, all the while pretending that she believes the wolf is her grandma, she tells the wolf that she needs to use the restroom. She assures him that she will be back, and so he does not worry, she
unfixes 
her woven red cap, and ties one end of the red thread on her leg and the other she gives to the wolf. The wolf agrees, but the little girl once out, unties the thread and runs away, for good.
And i think after that, she lived not bad, having learned how to recognize wolves, listen to her instincts, and plan escapes
