Seams biased against children. Parents are always right. While I understand why they do this, I don't think is OK. Also, for parents it ok to make logical errors?! WHAT?! I understand that this book is aimed at children, but double standards are not ok.
Some answers are not explained at all and in some cases I have no idea what I did wrong. Especially in the false dilema case when, I think, the answers are.... debatable (in some cases i don't think it's a false dilema because you don't really have a choice etc, but I don't know why it is in the mind of the author because it's not explained).
I wish the example where more carefully chosen and all the answers where explained.
Other than that, it's a good book that explains the subject well.
