This book contains fifty original puzzles guaranteed to please solvers at all skill levels. Each puzzle has a theme of interesting oxymorons like false-positive or jumbo-shrimp. Sometimes you'll identify the theme and use it to complete the crossing words. Other times the theme won't reveal itself until you have finished the rest of the puzzle. There are plenty of misleading clues, double meanings, and trivia questions to keep you on your toes. But overall, a good general knowledge and an appreciation for wordplay are all that is required to enjoy the book.
