Description 

Evil Agency SHADOW is really rocking the SHINE network. SHINE knows they are planning something but how are they sending their messages? Special Agent EJ12 must not miss a beat. This time she needs to find the code as well as pull the curtain down on SHADOW. That's the easy part. As EJ12, Emma Jacks can do anything. So why can't she perform with her friends at the school concert? Perhaps she can after all.
