It took Christian Bok 7 years to write Eunoia - the word is the shortest word in the English language containing all five vowels.
Eunoia means "beautiful thinking" and it's a very fitting title to Christian's book, in which each chapter uses only one vowel!
From CHAPTER A - FOR HANS ARP:
Hassan Abd al-Hassad, an Agha Khan, basks at an ashram - a Taj Mahal that has grand parks and grass lawns, all as vast as parklands at Alhambra and Valhalla. Hassan can, at a handclap, call a vassal at hand and ask that all staff plan a bacchanal - a gala ball that has what pagan charm small galas lack. Hassan claps, and (tah-dah) an Arab lass at a swank spa can draw a man's bath and wash a man's back, as Arab lads fawn and hang, athwart an altar, amaranth garlands as fragrant as attar - a balm that calms all angst. A dwarf can flap a palm branch that fans a fat maharajah. A naphtha lamp can cast a calm warmth.
