By Dan Brown, Author & Susan Batori, Illustrator. 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. For ages 3 and up.
