One of the most dangerous books in the history of paper, this particular tome was written by Gram Naa, a Black Magickian who loved crossword puzzles so much, that he used his powers of Magick to construct a book that would devise more and more complex puzzles. He put a little too much effort into it, though, since this book has puzzles that exists in more than one plane at once. Thus, even looking at any puzzle past page 2 will usually induce incurable insanity.
The first two pages, however, have been described as a "highly amusing way to spend an afternoon".
