ok, maybe not the book, but certainly the extracts on the bbc today page here. each chapter uses only a single vowel for all the words in that section. some examples are given, e.g.:
"Kingbirds flit in gliding flight, skimming limpid springs, dipping wingtips in rills which brim with living things: krill, shrimp, brill - fish with gilt fins, which swim in flitting zigs. Might Virgil find bliss implicit in this primitivism? Might I mimic him in print if I find his writings inspiring?"
please pay particular attention to the comments, e.g.:
"An arrant grab-bag; a bland, flat mass. Appals as far as charms. Alas, Art! That many days a man can scratch hard, and halt at that tat. That man wants a slap."
