Part of a series which covers a wide variety of educational topics from science to writing to music and math, and so on, this small volume looks like a children's book on the outside, but it really isn't - not unless that child is writing intelligently. Once they're ready for a nudge to the next level, this book will get them there. And it wouldn't go amiss as a gift for older writers too - not a few of them published ones!
Again I'm unconvinced of the value of the illustrations by Basher, but younger children might like them. Each page covers a different aspect of punctuation, in some detail, but not too heavily. The text is larger so it makes for easy reading both in seeing it and in following it. I recommend this for anyone who is interested in better using language - which ought to be all of us.
