My seven year old son wanted this book. He'd read it at school and really liked it. The 4U2read Barrington Stoke books were apparently written to help dyslexic children but from what I have seen they are suitable chapter books for all new readers. The print is easy to read, the vocabulary gently pushes the children on and the grammar is good (unlike many children's books, especially those based on TV series!!).
I used to help with listening to children read at my son's primary school and I know that this is one of the most popular books in the whole library for boys aged 6-8. There was always a waiting list for it and it was one of the few books that all the boys liked to read (even the ones who did not like reading). There was such a waiting list of boys, that I never actually saw a girl read it.
The story is about a boy who buys a video game from a spooky shop and then finds himself in the game with all the consequent life-threatening dangers. It is clever because it is arranged around getting to the next level, so every time the child completes a level, he's also just completed a chapter.
I would highly recommend this book for boys age 6 to 8 years
