"a paper star that has been unfolded and refolded into a tiny unicorn but the unicorn remembers the time when it was a star and an earlier time when it was part of a book and sometimes the unicorn dreams of the time before it was a book when it was a tree and the time even longer before that when it was a different sort of star" is the sixth paper star to be found, and the 53rd chapter overall.
