Eckler, a Ph.D. in mathematics, who with his wife, Faith, edits Word Ways magazine, has written a marvelous book for anyone who loves words and word play. Eckler includes explanations of acrostics, palindromes, anagrams, word squares, and word worms. There are pages of examples of each type of word play. A sample from the section on transforming one word into another through a word ladder changes less into more in five moves: less-loss-lose-love-move-more. The field of recreational linguistics has made great use of computer technology in the last few years, leading to more and more complicated word relationships, and the author expects great things to come in the future. Anyone who writes, does crossword puzzles, or plays Scrabble will find this book a gem. Recommended for public libraries.-Lisa J. Cihlar, Winfield P.L., Ill.
