Eunoia

[Paul McFedries]

One of my more interesting Christmas presents this season was a book called
"Eunoia.". It's written by Canadian poet Christian Bok, and it contains a
series of univocalic prose poems (each about 100 words). The first 20 or so
poems use only the letter A, the next 20 use only E, and so on through I, O,
and U. You can see an example here:

The back-cover copy claims not only that "eunoia" means "beautiful
thinking," but that it's the shortest word that uses all five vowels.
However, I can't find it anywhere, even in the OED. Is it a real word?
