Sixth grade was SO much easier for Danielle. All her friends were in the same room and she knew what to expect from her life. But now that she's in seventh grade, she's in a new middle school, her friends are in different classes and forming new cliques, and she is completely lost. When Danielle inherits a magical sketchbook from her eccentric great aunt Elma, she draws Madison, an ideal best friend that springs to life right off the page! But even when you create a best friend, it's not easy navigating the ups and downs of relationships, and before long Danielle and Madison are not exactly seeing eye-to-eye. To make matters worse, Danielle has drawn the head of her favorite (and totally misunderstood) cartoon villain, Prince Neptune. He's also come to life and is giving her terrible advice about how to make people like her. When she rejects him and he goes on a rampage during a school pep rally, Danielle and Madison have to set aside their differences to stop him!
