Listen, if you need help with punctuation, you probably need a big text book and several hours of serious study. No small, large print book will do the trick. However, if you want to brush up on a few things and smooth some rough edges, this book helps. The author is quite energetic and over-zealous about punctation (commas, colons, etc.) and its proper use; don't let that scare you off. It is filled with several quick lessons and facts that bring the whole puntuation picture together, piece by piece. It is a quick read and a fun one too. It is not the Bible of english grammar or punctuation, but what is? (i.e. everyone is in disagreement, everywhere)If you want to quickly brush-up and move on, read it. If you want to be over-zealous yourself, write your own book.
