“The question was why. And to that question she had no answer. Not even a clue. It was just another proof of J. R. R. Tolkien’s observation: you must be careful each time you step out of your door, because your front walk is really a road, and the road leads ever onward. If you aren’t careful, you’re apt to find yourself…well…simply swept away, a stranger in a strange land with no clue as to how you got there.”
