Does she have the "Darth Vader and Son" and "Darth Vader's Little Princess" books? DD7 is obsessed with them at the moment. They are pretty simple reading, but the humor is awesome -- each page is like a Far Side cartoon, practically.

What's funny is that she's never even seen Star Wars -- she only picked up on it from Angry Birds! But I'll be surprised, given the current obsession, if she doesn't end up wanting a Jedi costume or something Star Wars for Halloween.
