The BBC gives a kind review of Eunoia:

Eunoia is the shortest word in English containing all five vowels – and it means “beautiful thinking”. It is also the title of Canadian poet Christian Bok’s book of fiction in which each chapter uses only one vowel.

Mr Bok believes his book proves that each vowel has its own personality, and demonstrates the flexibility of the English language.

I can barely read the excerpts. In fact, I might almost say I find it a little Eunoia-ing. Ok, bad pun.

Gulls churr: ululu, ululu. Ducks cluck. Bulls plus bucks run thru buckbrush; thus dun burrs clutch fur tufts. Ursus cubs plus Lupus pups hunt skunks.

Funny sounding stuff, but there is no way I would want to read a whole book of it unless it had really pretty pictures and maybe some pop-up art. I guess the advantage is rhyming comes so easily when you focus on a single vowel.

Because I could not stop for death,
He kindly stopped for me;
The carriage held but just ourselves
And immortality.

We slowly drove, he knew no haste,
And I had put away
My labor, and my leisure too,
For his civility.

We passed the school, where children strove
At recess, in the ring;
We passed the fields of gazing grain,
We passed the setting sun.

Or rather, be passed us;
The dews grew quivering and chill,
For only gossamer my gown,
My tippet only tulle.

We paused before house that seemed
A swelling of the ground;
The roof was scarcely visible,
The cornice but a mound.

Since then ’tis centuries, and yet each
Feels shorter than the day
I first surmised the horses’ heads
Were toward eternity.
