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.

by Robert Bridges

When men were all asleep the snow came flying,
In large white flakes falling on the city brown,
Stealthily and perpetually settling and loosely lying,
Hushing the latest traffic of the drowsy town;
Deadening, muffling, stifling its murmurs failing;
Lazily and incessantly floating down and down:
Silently sifting and veiling road, roof and railing;
Hiding difference, making unevenness even,
Into angles and crevices softly drifting and sailing.
All night it fell, and when full inches seven
It lay in the depth of its uncompacted lightness,
The clouds blew off from a high and frosty heaven;
And all woke earlier for the unaccustomed brightness
Of the winter dawning, the strange unheavenly glare:
The eye marvelled — marvelled at the dazzling whiteness;
The ear hearkened to the stillness of the solemn air;
No sound of wheel rumbling nor of foot falling,
And the busy morning cries came thin and spare.
Then boys I heard, as they went to school, calling,
They gathered up the crystal manna to freeze
Their tongues with tasting, their hands with snowballing;
Or rioted in a drift, plunging up to the knees;
Or peering up from under the white-mossed wonder,
‘O look at the trees!’ they cried, ‘O look at the trees!’
With lessened load a few carts creak and blunder,
Following along the white deserted way,
A country company long dispersed asunder:
When now already the sun, in pale display
Standing by Paul’s high dome, spread forth below
His sparkling beams, and awoke the stir of the day.
For now doors open, and war is waged with the snow;
And trains of sombre men, past tale of number,
Tread long brown paths, as toward their toil they go:
But even for them awhile no cares encumber
Their minds diverted; the daily word is unspoken,
The daily thoughts of labour and sorrow slumber
At the sight of the beauty that greets them, for the charm they have broken.
