Two identical twins. An ancient castle.
A doorway that should never have been opened. Charlie and George are about to begin their first year at a remote boarding college, leaving behind everything familiar. But hidden beyond the college grounds, deep within an enchanted forest, lies a secret that has waited a century to be discovered. Behind the walls of an abandoned house, a concealed doorway leads to another world - a vast green forest and a quiet white village where satyrs live in fragile peace. There, the twins form an unlikely friendship with Billy and his wife, Octavia. Yet something dark stirs beneath the beauty. In the caves beyond the village, a Beast watches. Satyrs who wander out after nightfall disappear without a trace. Whispers spread. Fear grows. And the Beast is far more than a monster lurking in the shadows. As Charlie and George are drawn deeper into this hidden world, they must uncover the truth before the darkness escapes the forest - and follows them home. A spellbinding fantasy adventure filled with mystery, danger, and the courage to face what lies beyond the door.
