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.

In Dragon of the Red Dawn, Mary Pope Osborne transports readers back to the splendor, rich culture, and magic of traditional Japan.
