You've heard of Jekyll and Hyde, you've heard of the Invisible Man, but have you heard of Castle Bran? Eve, Griffin, Hal and Ren are whisked away to Transylvania, to the supposed home of Dracula himself. Lured there by a desire to understand more about their true natures, our foursome are instead plunged into the midst of a deadly mystery. Children are going missing, townspeople are being brutally killed and a suspicious stranger keeps appearing from the shadows. Meanwhile, Ren is trapped in Castle Bran, where his fate lies in the hands of a strange - yet oddly familiar - host.
