"What is this?"

There is a place where the world ends.
There were an impossible number of tiers.
"This is impossible," I said.
How could there be so many? How could the Earth contain this?
Maybe it was a trick with mirrors. Lenses, lasers, and lazy-susans.
It couldn't be real.
Adonie didn't appear to doubt it.
She didn't seem to take it in except as a definition
of what lay between us and Olive.
