With her friend, 20th Century Katie finds a strange, overwhelmingly enticing, blue door, which appears steeped in history and magic. Mystery, intrigue, riddles-and perhaps romance-may lurk behind it, if the fates are with them. A halo and a click, and the door opens of its own accord. The people who dwell behind this mysterious portal seem obsessed with the concept of time travel. Perhaps they are living in a fantasy world. Then again. Perhaps they are not.
