Take the Fair Face of Woman, and Gently Suspending, With Butterflies, Flowers, and Jewels Attending, Thus Your Fairy is Made of Most Beautiful Things by Sophie Gengembre Anderson [Public domain], via Wikimedia Commons
Fairies are spontaneous and troublesome and usually a great deal of fun. They have been around since Celtic times and have been everything from fallen angels to demons, depending on the source.
Enter Walt Disney. Between the Blue Fairy that makes Pinocchio a real boy and Tinker Bell, Peter Pan's side-kick, the fairy has become something new. Neither of these stories was written by Mr. Disney, but he brought them to the big screen in the Disney fashion we've all come to know and love. And thereby, he changed a once-demon into a magical, mystical, lovable character.
If you're longing to read more about the fae, I strongly recommend the Avalon series by Marion Zimmer Bradley. Her fairies may not look like Tinker Bell, but the stories are enthralling. You might also love the Bronze Canticles trilogy by Tracy & Laura Hickman as much as I did.
