Perhaps you’ve heard of “A Void”, the novel by Georges Perec that is written entirely without the letter ‘e’ (save for the byline, of course). But have you heard of Eunoia? It’s a book with five chapters. The first is composed of words containing only the letter ‘a’. The second using only ‘e’. The third using only ‘i’, and so on. You can read the whole thing at the link above, which is good, because it appears the site for taking orders is no longer operational.
