I read this today over at DIAGRAM. I liked it a lot. It’s crazy inventive in so many ways, but mostly I thought, who would think of not making pocket plural? It integrated into the story so well, and the author got so much out of it. In a note about the piece at the very end, Tim Horvath says, “(((()))) If the string theorists are right, the universe teems with hidden dimensions; pockets abound. To make even a single new one, then, is to play at being God,” which is an amazing thing to say, I think.
So, read that, I would suggest.
