SO I just finished reading Geekerella by Ashley Poston - and I have to say that this is a modern sequel to Cinderella.
You have Daniella and her horrible evil stepmother and two stepsisters - and Darien the actor who plays the lead character in the Movie that her father and mother used to love. In fact her father started a Con for the TV show.
You have a Pumpkin, a "fairy godmother"- a dog.
I don't want to go in to detail - but it shows the flaws in the characters and their good parts.
A REALLY great story - no sex. So if you have a pre teen - I highly recommend this one!
