This book is really good - I got as a present for my brother instead of an Easter Egg as he doesn't like chocolate that much and I knew that he would get other eggs anyway.
When they say 'glitter', they are not joking - there is glitter almost everywhere on each page which makes reading a more sensory activity as the shininess of the glitter is eye-catching and he can feel the texture of it too! DON'T PANIC - the glitter stays on the page!
The only downside is that it is quite a short story (hence only 4 stars) but as I said, it is also a sensory activity so that helps amuse him. =D
