When children turn into tweens, they seem to make a sudden transition from fairy tales to books about wizards and vampires. While reading something that starts with "once upon a time" seems childish, there are actually several valuable life lessons found among those pages. Of course, you can't give your soon-to-be-teen a picture book and expect them to get excited. Instead, hand them one of these more age-appropriate reads that are based off their favorite fairy tales. After all, happily ever after doesn't have to have an age limit.
