After the battle of the Neptunius, Helen Parker has been expelled from Elmoon. Hidden in the mountains, she will discover unpleasant news about her past that will make her rethink if she wants to continue to have powers or if she should lose her magic forever.

During her exile, Brooklyn Scales will visit her. The dragons and the Moonstone are in grave danger, and together they will go on a long journey to search for new magical allies. Meanwhile, James will have to consider his loyalties: both The Guard and Helen have turned their backs on him, and everything around him seems like a big lie.

However, Mortimer has plans that will destabilize the entire wizarding community. He has discovered a weapon that has even more power than himself and will do everything possible to get hold of it before it is too late. The countdown has begun and only one of the two can make it out of the dragon cage alive.
