This is larger than the usual CTS pamphlets, being an A5-sized book, of about 88 pages.
It is designed as a Handbook for parents, and in particular to help them to answer their children's questions, and then use those questions as a starting point for deepening faith.
The book is in three sections: Creation and Created; Knowing God, and Catholic Life and Times. That makes sense, I suppose, but I did think it odd that it did not follow the structure of the Catechism (and the preceding Catechism, from Trent, come to that). I will return to this point.
Each of these sections has five chapters: so Creation and Created, for example, has chapters on God and Creation, Angels, Saints, Holy Souls and Mary.
Each chapter is made up mainly of the types of questions that children ask, with reasonably full explanatory answers: longer and fuller than the old Penny Catechism, for example. So the first Chapter, on God and Creation, has questions such as: Who made God? Why did God create Satan, and Why did Adam and Eve spoil everything? The answers are good: clear and accurate, and suitable for reading to and discussing with children.
Each chapter also includes, at the end, two further sections. The first is Points to Ponder: these are a few deeper questions for the parents to ask themselves and discuss; the second is Practical Application: a few suggestions for things to do as a family, to build on the lessons of the chapter.
The layout is clear and sensible, and nicely illustrated with children's drawings (so much better than the faux-naif drawings such books occasionally use).
However, I was struck by the huge gaps. In a sense that is inevitable in a work of this size, but I found it very odd that it discusses relative trivia in some detail (Why do we give eggs at Easter?) whilst omitting (for example) anything about the Sacramental system, and so on. I think this flows from my comment earlier that the authors did not follow the structure of the Catechism. By making their own structure up, the risk was always going to be that some things fell through the cracks.
My other gripe is the lack of an index. If my child raises a question about baptism, for instance, how do I know if there is anything in here about it. There is no chapter on the Sacraments; is it in the one about Prayer? Or the one about the Mass? Or somewhere else? That seems to me a missed opportunity. Also, references to Catechism paragraphs would be extremely helpful.
Nonetheless, what is here is good and this is certainly a useful book to have on the shelf; so I recommend it with the caveat that it misses a good deal which you really should teach your children, so you will certainly need other resources (such as the Catechism or Youcat) to supplement it.
