Jack and Annie travel back to nineteenth-century Ireland to inspire a young Augusta Gregory to share her love of Irish legends and folktales with the world.
As a thank-you from Merlin and Morgan, Jack and Annie are sent on what should be a vacation at a luxurious resort in Cozumel, Mexico, but is, by mistake, an adventure with ancient Mayans, instead.
Two children, Jack and Annie, discover a mysterious tree house and are swept away to the world of the dinosaurs, a medieval Great Hall, a tomb in ancient Egypt, and a pirate ship, unsure how to get home.
