Emmy in the key of code
(Book)

In a new city, at a new school, twelve-year-old Emmy has never felt more out of tune. Things start to look up when she takes her first coding class, unexpectedly connecting with the material-and Abigail, a new friend-through a shared language: music. But when Emmy gets bad news about their computer teacher, and finds out Abigail isn't being entirely honest about their friendship, she feels like her new life is screeching to a halt. Despite these obstacles, Emmy is determined to prove one thing: that, for the first time ever, she isn't a wrong note, but a musician in the world's most beautiful symphony. -- from Amazon.
