NEW YORK TIMES BESTSELLER • In his interactive picture book debut, the world-renowned author of The Da Vinci Code invites young readers to discover life lessons from the symphony that is the animal kingdom. Includes hidden puzzles plus a free app with music composed by Dan Brown!

“Brown does not disappoint. . . . A delightful musical debut sure to be a hit at story hours.”—School Library Journal, starred review

Travel through the trees and across the seas with Maestro Mouse and his musical friends! You’ll meet a big blue whale and speedy cheetahs, tiny beetles and graceful swans. Each animal offers a special secret: about emotion regulation, social awareness, mindfulness, and many more important life skills.

Along the way, you might spot the surprises Maestro Mouse has left for you—a hiding buzzy bee, jumbled letters that spell out clues, and even a coded message to solve!

Children and adults can enjoy this timeless picture book as a traditional read-along, or can choose to listen to original musical compositions as they read—one for each animal—with a free interactive smartphone app, which uses augmented reality to play the appropriate song for each page when a phone’s camera is held over it.

The author will be donating all U.S. royalties due to him to support music education for children worldwide, through the New Hampshire Charitable foundation.
