"Stay golden, Ponyboy." I'd call S.E. Hinton the John Green of the 70s--books shared from friend to friend, kind of hidden from parents. Now The Outsiders is taught in our 7th grade classes! The Outsiders is her best book, but readers will usually return to read That Was Then, This is Now, too. The Socs and the greasers are still with us, just with different names.
