1 New York Times bestselling author Dan Brown makes his picture book debut with this mindful, humorous, musical, and uniquely entertaining book!

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

Travel through the trees and across the seas with Maestro Mouse and his musical friends! Young readers will meet a big blue whale and speedy cheetahs, tiny beetles and graceful swans. Each has a special secret to share.

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.
