From the developer:
You're no stranger to paranormal visitors showing up at Midnight, but when a suspicious character drops a threat in your mailbox, you're drawn into the timeless struggle of good versus evil. You will use books to travel through space and time, as you join Charles Dickens and Washington Irving on an exciting adventure through their most famous books. Your goal is to unmask the villain in time.
