Stephen King’s The Dark Tower: A Concordance, Volume One

From hundreds of characters to Mid-World geography to the High Speech lexicon, no self-respecting Dark Tower fan will want to be without this comprehensive handbook to the first four books in the series. As Stephen King himself explains in the introduction, he commissioned the concordance for his own private use while writing the final three books. When he found Robin Furth's work to be 'entertaining and invaluable' he immediately recommended the manuscript for publication.
