In the heart of Transylvania, where shadows never sleep, Isabel Marina, a young history student, arrives at Bran Castle to investigate the archives hidden for centuries under its cold stone. Among forbidden manuscripts and symbols that no one understands anymore, she discovers a set of cryptic texts - relics of a truth that should not have been dug up. Far away, Stephan Velmoor feels his blood stirring, like a storm called by a voice he has never heard, but that he recognizes. Since Isabel was invited to Bran, his peace has been shattered, and the beast inside him, asleep for centuries, has awakened - hungry for life, hungry for her. A fierce battle is raging inside him: the creature wants her destroyed, the man would do anything to save her. As Isabel penetrates the secrets of the manuscripts, fate catches them in a web of passion, blood and silence. Because between love and curse, the line is thinner than a whisper. "Some secrets cannot be deciphered. They just wait for the right blood to be reborn."
