In the magic treehouse series, not only in Merlin Missions, Jack and Annie found a magic treehouse. They soon discovered that in the magic treehouse there were lots of books and when they point to a picture in the book and make a wish to go there the magic treehouse just magically transports them there! They soon learned that the treehouse belongs to Morgan Le Fay from Camelot. Jack and Annie have helped Morgan with a humongous amount of missions in all places and time periods with the help of the magic treehouse. However in Merlin Missions it is not however Morgan that sends them on these missions. It is Merlin, a fantastic magician. During Merlin Missions, Jack and Annie make two friends named Teddy and Kathleen. They soon completed four missions that showed they could properly handle magic. On those missions, they were given a book of ten magic rhymes to use on four missions. Each rhyme can only be used once. Since they succeeded in those four missions, they were given the Wand of Dianthus. A magic wand that could create magic. Soon Merlin was not well, and not cheerful at all. Jack and Annie found four secrets of happiness for him, and now he is happy again. However the biggest thing that cheered him up was a little penguin Jack and Annie had gotten from their last mission to find the last secret of happiness for Merlin. That mission had taken place in Antarctica.
In this book Jack was just getting ready for dinner when Annie told him the magic treehouse was back! He took the Wand of Dianthus, and hurried after Annie on their way to the magic treehouse. In the treehouse, when they saw Teddy and Kathleen they greeted each other warmly. Teddy and Kathleen turned the Wand of Dianthus into a magic flute for this adventure. When danger comes, they said to blow on the mouthpiece, and it will play automatically for you when you blow on the mouthpiece. They also said that while one of you play, the other one has to sing. Whatever that person sings, it will come true. However this magic flute can only be used once. Before the magic they turned the Wand of Dianthus into a magic flute, Teddy and Kathleen gave Jack and Annie a royal invitation that said they were invited to a party in the summer palace at five o’clock in the evening! Jack asked if there was a research book they could use, but Teddy and Kathleen said to rely on your talents and wits whatever that means. Teddy and Kathleen also said on this mission they will bring happiness to millions and millions of people! Then Teddy and Kathleen left leaving Jack and Annie with a magic flute and a royal invitation to the summer palace. Since they wanted to get started with the mission, they pointed at the invitation and made a wish. The magic treehouse landed right in where the mission was taking place. But there outfits! They were ridiculous! They were the craziest outfits they ever wore! Jack’s wig was itching his head like crazy! Jack and Annie soon got out of the treehouse. They went to the Summer Palace, showed a guard their tickets, and got in. They soon figured out that they were going to meet the Her Imperial Majesty! She is a very, very, very, important person! Jack and Annie don’t know what to do so they decide to copy what all the other people do. But then they forgot to watch the other people, and soon it was their turn! Oh, what are they going to do? They don’t know what to do when they meet Her Imperial Majesty, maybe most important person in the world! This is not all, soon they met a little boy who gets Jack very annoyed, and soon he ran away! They had to find him because his kind sister begged them, so they said yes. When they found him, they had scary animals all around them so they used the magic flute! The good thing is that they are rescued from the animals. The bad news is that they wasted all their magic on this mission on a annoying little boy! What are they going to do? How will finding and saving a little boy give bring millions and millions of people happiness like they are supposed to do?
