Prologue

One summer day in Royal Woods, Michigan, a mysterious tree house appeared in the woods. Lincoln Loud and his 10 sisters soon learned that the tree house was magic-it could take them to any time and any place in history. They also learned that the tree house belonged to Morgan le Fay, a magical librarian from the legendary realm of Camelot.

After Lincoln and his 10 sisters traveled on many adventures for Morgan, Merlin the magician began sending them on "Merlin Missions" in the tree house. With help from two young sorcerers named Teddy and Kathleen, Lincoln and his 10 sisters visited four mystical places and found valuable objects to help save Camelot.

On their next eight Merlin Missions, Lincoln and his 10 sisters once again traveled to real times and real places in history: Venice, Baghdad, Paris, New York City, Tokyo, Florence, the deep ocean, and Antarctica. After proving to Merlin that they could use magic wisely, they were awarded the Wand of Dianthus, a powerful magic wand that helped them make their own magic. With the wand, Lincoln and his 10 sisters were able to find four secrets of happiness to help Merlin when he was in trouble.

Now Lincoln and his 10 sisters are waiting to hear from Merlin again….
