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.
