Welcome to the third installment of the Sunshine-Mary Sudoku book series! As with the previous books, this book is designed to engage those who may feel they are cognitively not as "sharp" as they once were. The book's format has been thoughtfully created; it is designed to be easily handled, even by those who have limited dexterity due to severe arthritis, and the large print enables those whose visibility is less than optimal to be able to delight in the solving of sudoku puzzles. They are a wonderful gift for yourself or the ones you love. Enjoy..........
