His Sister's Babysitter

When Ellie Collin's mother comes home to tell her she is babysitting for a little girl she's never even met, Ellie's not so excited. Also, the fact that she's going to spend mostly everyday for the rest of the summer, before high school, with this girl, Ellie would rather shop with her best friends. When Ellie finds out that one of the hottest guys at her old school is the girls brother, she isn't as thrilled as she should be. This is going to be one crazy summer.
