I just finished Anne Carson's Nox, which was a Christmas gift from one of our oldest family friends and his wonderful girlfriend who is a famous novelist. On the back of the "book," Carson describes her work thus: "When my brother died, I made an epitaph for him in the form of a book. This is a replica of it, as close as we could get." I put the word "book" in quotations marks because this work is not, strictly speaking, a book. It is, rather, a box with a fold out visual-and-prose poem and at the same time, an associative reading of Catullus 101.
I don't want to spoil it; I suggest you read it. Her work is wonderful.
