Keena Ford and the Secret Journal Mix-Up

Second-grader Keena Ford loves writing in her journal. One day, Keena accidentally leaves her journal in the apartment of her mean classmate Tiffany Harris. The next day, Tiffany informs Keena that she's read the journal and is going to tell all of Keena's secrets! Well, unless Keena does everything Tiffany says, of course.
With a little help from her brother, some classic fables, and a visiting author, Keena discovers what she must do to stand up to Tiffany and apologize to her friends.
