Emma McDougal and her friends go on a quest of a lifetime to find and help Father Time. They are to find the magical unicorn, Chelsea, before the evil Grissel gets his hands on her. Chelsea holds the key to stopping all of time. If the warlock gets this 'key' he will use the world in ways no one can imagine. Evil would prevail over all of good.
Father Time shows them four doors that glide in the air. One leads to the past, one the present, one the future, and one to The Other World where mysterious creatures really do exist. They find themselves in the Jurassic Period with lots of dinosaurs, and they have to fight their way out of this prehistoric world and back to Father Time's realm.
In The Other World the children travel through vast, beautiful lands and islands. They meet flying birdmen and hear stories of talking apes, unicorns, and other creatures. The Melancholians, the birdmen, give the children a map of the world and direct them to Cornia--where unicorns live.
Join Emma and her friends on an exciting adventure in a race to save the world from the evil Grissel in Emma McDougal and the Quest for Father Time.
