ROTALEVER REVELATOR is a book made from words that spell other words backwards: a giant palindrome that contains poems about geography, dams, swamps, celebrities, eponyms, and the news. There's also a translation of the first part of "Burnt Norton" and a multi-lingual section, "O Rue Euro," with German, French, Italian, and Spanish beating up on English, and vice-versa. Flip the book over, and you have Revelator Rotalever: the same sequence of letters, differently divided into words and punctuated. Doug Nufer's stop-at-nothing inventiveness, an object lesson in transforming the merest opportunity into delight, is matched here by James Siena's stylish illustrations.
