Nightdream Academy is under total lockdown. Calamity has consumed all of Mena’s homeworld, and now it threatens to consume the universe itself. Anguish the Blood Siren has succeeded in corrupting the dream world into a complete nightmare…or has she? Before he was consumed by the Nightmare Void, Gemini, the former headmaster, spoke of a legendary pair of heels—the Dream Heels—with a power to negate the power of nightmares lying deep within the academy. Unfortunately, the Dream Castle is a labyrinth of countless passages and rooms, some even unknown to the current staff. It’s up to Mena and her friends to unlock the Dream Heels, but they must hurry, not only are students disappearing within the confines of the school, but Mena is hearing mad crying at night…or is it laughing? Sooner or later, she will have to confront her mother, and learn the true reason of the tears of Anguish.
