Book excerpt: What’s better than a crossword? That’s right: a crossword with no black squares! Well, actually, there are black squares, but you have to figure out where they go using the clue’s number and your own wits. And the best part is, when you’re done, some of the crosswords will reveal a picture related to the puzzle’s theme! Veteran New York Times puzzlemaker Brendan Emmett Quigley constructed each grid, so you know you’re in for the freshest, hippest puzzles with the most devious clues.
