Eunoia is a book that tells the story, in a way, of vowels:
It is the shortest word in English that contains 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.
It abides by many rules:
All chapters must allude to the art of writing. All chapters must describe a culinary banquet, a prurient debauch, a pastoral tableau and a nautical voyage. All sentences must accent internal rhyme through the use of syntactical parallelism. The text must exhaust the lexicon for each vowel, citing at least 90% of the available repertoire.
An excerpt from 'Chapter O':
"Loops on bold fonts now form lots of words for books. Books form cocoons of comfort - tombs to hold bookworms. Profs from Oxford show frosh who do post-docs how to gloss works of Wordsworth. Dons who work for proctors or provosts do not fob off school to work on crosswords, nor do dons go off to dorm rooms to loll on cots. Dons go crosstown to look for bookshops known to stock lots of top-notch goods: cookbooks, workbooks - room on room of how-to books for jocks (how to jog, how to box), books on pro sports: golf or polo. Old colophons on schoolbooks from schoolrooms sport two sorts of logo: oblong whorls, rococo scrolls - both worn on morocco."
