Em and Schroedinger are desperately trying to find Peter, which brings them to the ancient tower of Babylon...only Babylon isn't so much a what as a who. And just when they think they're about to get some answers, a host of shadow warriors shows up, grabs Em, and high tails it across the plain. Except Em has a few tricks up her sleeve and things don't go quite according to the shadows plans. Do they ever?
