Hi. Author here! Well, you might well understand that I'm just a tiny bit biased!
I have given the book to my own nephews and neices, and they have found it more accessible than other programming texts.
I was only willing to compromise so much -- since most of the audience out there is pretty demanding on what a book to cover everything, including very sophisticated and state of the art features (there are tech reviewers who slime you if you omit anything)!
But my goal with this book was to take people from the very, very beginnings of learning to program. I thought of all the pot holes I had to steer around many, many years ago.
One of the things I've always been most proud of is the step-by-step diagrams in the first few chapters. (These are going to be skipped by more advanced readers.) It was my way of taking the most basic conceptual features of programming and illustrating them in the easiest way.
Still, depending on how precocious a child is, I suspect that he or she might use some person-to-person help. Problem is, I can't clone thousands of copies of myself and beam them into people's living rooms or class rooms.
