If you like to do acrostics puzzles, these are very good. If you don't like to do acrostics puzzles, then this is not the book for you. If you want to try doing acrostic puzzles, then why not give it a whirl. The price is right and what do you have to lose besides about ten bucks and a lot of damage to your already oversized ego if you find they are too tough for you. So good-bye and good luck.
