After the events of Nightmare, Eden and Darius are finally together, even if their forbidden relationship must remain a secret. Their separation becomes even more difficult to navigate as the darkness taking over the Dream Realm gradually increases, stealing the light and trapping Mortals in their dreams. Soon a different type of magic begins to threaten their paired union, one that is not only robbing them of their powers but which could separate them if they don't find a way to stop it. Despite their diminishing powers, Eden and Darius are determined to discover the source of the darkness and find a way to stop it from completely destroying the balance of the Dream and Nightmare World forever.
