The TAG reading system is a really clever system that allows you to press a "pen" onto the page of these special books and have the book read to you. It can either read word by word, the whole page or indeed the whole story depending upon what you choose.
This TAG book follows Diego and Alecia on a mission to discover the identity of a "mystery fish". My kids are big Diego fans and, despite being very familiar with this episode of the Diego cartoon, (to which it is very true), they still love reading this story over and over. There are, as usual, lots of lovely extra little noises in to discover in the pictures and the games at the back of the book have kept the boys occupied for hours. This system has proved to be quite educational - my older child quite often uses the pen to read word by word, or gets it to read the whole page and then reads along with it, whereas the little one just loves listening to the story and pressing on the pictures to activate the different sounds.
All in all, highly recommended - especially for the younger users of this system!
