Allison and Sam catch a cab to The Hand's place. They chit-chat along the way. He says a little bit about how La Garra used to be a city in the sky, and Fort Black was down on the ground below it. That's about it.
The author has been hinting here and there for a WHILE now about La Garra being up the sky, and I still have no idea how the heck that would even be possible.
