Ember Shadows lives in a world full of magical realms and curious creatures. And untill recently, it was all completely secret. But now things are changing. People have heard about the hidden realms and are desperate to see them. They're so desperate that the Emocean - the ocean that controls emotions has started making far, far too much greed. Extreme greed is poisonous. With the magical realms and creatures at risk of being devoured by a creeping green venom, Ember and her friends must find a way to protect the landscapes... before it's too late.
