For true puzzle fans, Sunday isn't Sunday without an extra-large, extra-stimulating crossword-and it's the ideal mental fitness routine, too. So, in conjunction with AARP, Stanley Newman, one of America's leading crossword constructors, has created a fabulous collection that gives solvers a Sunday challenge every day of the week. Each crossword features a theme-and until the solver discovers what it is, the clues to the longest answers in the grid will remain baffling. It's more puzzle fun than you can have in a month-or year-of Sundays.
