My youngest daughter recently read Hello Stars by Alena Pitts.  Since it is a book written towards children, I am giving her the driver's seat on this one. Go ahead and read her review about Hello Stars.

Batgirl at Super Hero High was our first DC Comics experience.  The girls had never shown interest in comic books, and I honestly hadn't thought much about this reading option.  I am glad that we ventured into this new realm of storytelling though because they were drawn into the story especially my nine year old daughter.
