Merlin Mission Collection: Dragon of the Red Dawn / Monday With a Mad Genius / Dark Day in the Deep Sea / Eve of the Emperor Pen

Dragon of the Red Dawn: Merlin the Magician will not eat or sleep or speak to anyone in Camelot. What can be done? The enchantress Morgan knows who to ask for help: young Jack and Annie of Frog Creek, Pennsylvania! The brother-and-sister team quickly head off in the magic tree house on another magical and historical adventure. Their mission: discover one of the four secrets of happiness. Their journey: to a land of fierce samurai and great beauty, the capital city of Edo (now the city of Tokyo), in ancient Japan in the 1600s. Their tools: a research book to guide them and a magic wand with three special rules.

Monday with a Mad Genius: Jack and Annie are on a mission to save Merlin from his sorrows! The brother-and-sister team travel back in the magic tree house to the period known as the Renaissance. This time, Jack and Annie will need more than a research book and a magic wand. They’ll need help from one of the greatest minds of all time. What will they learn from Leonardo da Vinci?

Dark Day in the Deep Sea: Jack and Annie continue their quest for the secrets of happiness—secrets they need if they’re going to save Merlin. But when the magic tree house leads them to a tiny deserted island in the middle of the ocean, they’re not sure who needs help more—Merlin or themselves! The brother and sister team are soon rescued by a ship of explorers and scientists. But the crew isn’t looking for the secrets of happiness. The crew is looking for . . . a sea monster!

Eve of the Emperor Penguin: Jack and Annie arrive on the one continent they haven’t visited before: Antarctica! What can they hope to learn about happiness in such a barren place? Only the penguins know for sure… Jack and Annie are about to find out!

Moonlight on the Magic Flute: Jack and Annie head to 18th-century Austria, where they must find and help a musician by the name of Mozart. Decked out in the craziest outfits they’ve ever worn—including a wig for Jack and a giant hoopskirt for Annie!—the two siblings search an entire palace to no avail. Their hunt is further hampered by the appearance of a mischievous little boy who is determined to follow them everywhere. But when the boy lets the animals out of the palace zoo, Jack and Annie have to use the only magic at their disposal to save themselves and the naughty little fellow.

A Good Night for Ghosts: Jack and Annie are on a mission to find—and inspire—a musician that brings happiness to millions of people. After traveling to New Orleans, Jack and Annie come head to head with some real ghosts, and discover the world of jazz when they meet a young Louis Armstrong.

Leprechaun in Late Winter: Jack and Annie are on a mission to find (and inspire!) creative people. This time, Jack and Annie meet an Irish girl and go on a magical adventure that changes the girl’s life—she grows up to be Lady Gregory, who helped bring back the Irish legends, started a theater, and helped the Irish people regain both their heritage and their pride.

A Ghost Tale for Christmas Time: Jack and Annie must help the famous writer Charles Dickens! The brother and sister are whisked back in time to Victorian England and the foggy streets of London. There, Jack and Annie discover that Charles Dickens has been thrown in jail! How can they help him? They will need all their magic—and help from three ghosts—to keep the great writer from ruining his life!
