I've not heard of anything like this before, were you can read the book and also go on the app. I think it is a good way to learn the child to read and use a compute/laptop. Whilst they are having fun they are also learning.
This book is aimed at 8-13 year olds. There are many children these days who have no interest in reading books what so ever. This book is aimed to make children enjoy reading more.
I would really recommend this book to any parent if they would like their children to be more interested in reading. I have given the book my friend's son and there will soon be an extra bit to this review on what he thought about the book! I will keep you all updated.
Otherwise, take a look on Jack Hunters website which you can view here.
