The book is about a young girl named Lucy who, upon finding out that the market is closed, decides to travel around the world in order to find the ingredients she needs for her apple pie.
The students become travel agents, create their own travel agency, and support Lucy throughout her journey.
The travel agents work with maps to design the best routes and means of transportation for the journey. They gather useful information for Lucy about each country she will visit.
Through email exchanges, the students give her advice as she travels from place to place.
Lucy encounters unique challenges in each country that the travel agents help her to overcome.
Upon returning home, Lucy sends the travel agents an apple pie, made with the delicious ingredients she has collected. As the travel agents enjoy the pie, they reflect on the ingredients and Lucy’s amazing journey.
