The Three Races must work together if they are to survive, but they have another problem – Castallan. The traitorous wizard has raised a deadly rebellion and declared himself King of Humans. He believes himself safe in the bowels of his impenetrable Bastion fortress, but Darnuir, now King of Dragons, intends to break those walls at all cost. To face these threats, all dragons, humans and fairies must truly unite; yet old prejudices may undermine Darnuir’s efforts once again. And as the true intentions of all are revealed, so too is a secret that may change the entire world.
