Actually, I have high expectation for this book when I heard about it. But upon receiving it, it did not meet my expectation. I was expecting that it has more words, stories, tips, but I guess it is not meant for my 6yo son who has been reading heavy contents. I want him to be exposed to science materials as in this case something related to space in tandem with teaching him Islam, moral values, etc. But this book does not reach that level. It is good for babies to 3-4 yo.
