Inside the tree house, Annie was holding a book about knights and castles. She pointed to the picture with a knight riding toward a castle. The tree house spun and then Jack and Annie heard neighing of horses. Looking out the window, they saw a knight in armour. He is riding on a black horse toward an old castle.

Annie was excited to visit the castle and get to know the knight. How about Jack? What adventures would these two kids have this time?
