Penelope is running out of time!

She dreams of being a writer, but how can she pursue her passion when her strict, obsessive mother schedules every minute of her life? And how will she ever prove that writing is worthwhile if her mother keeps telling her to "get busy!" and "be more productive"?

Then one day, Penelope discovers a hole in her schedule-an entire day completely unplanned!-and she mysteriously falls into it. What follows is a mesmerizing journey through the Realm of Possibility where Penelope sets out to find and free the Great Moodler, the one person who may have the answers she seeks. But a menacing shadow tracks Penelope's every move. With darkness on her heels, she must face an army of Clockworkers, battle the evil Chronos, take a daring Flight of Fancy, rescue her friend, Dill, and free herself from the grip of time.
