[A]: Negative

[Q]: I am a complete Sudoku addict and am very disappointed with this book. The only reason I bought it was because I was desperate for more puzzles and it was the only one available at the store I was in. First of all, it costs $4.99 which to me, is way too much money when you can get a Kappa book for $1.99 which has better puzzles. Another thing that bugs me about this book is that some of the answer keys in the back don't match the corresponding puzzles. When I get to the difficult/Very Challenging ones in the back, sometimes I need a little help! But unfortunately, this book has quite a few errors in the answer section so when I've hit a dead end, it's over.I would recommend Kappa books from your local supermarket. This simply costs too much money for not mush quality.
[A]: Negative

[Q]: In general, I have little appreciation for humor based on male parental incompetence. Furthermore, ... I have just as little time for humor based on female mechanical incompetence. The theme of this book is male incompetence when it comes to pregnancy and birth. Many of the cartoons are about men being nincompoops in the delivery room, doing such helpful things as fainting, getting sick when looking at the placenta and so forth. ...Some of the cartoons about the baby in the womb are a bit humorous, but overall I did not find this collection of jokes very funny.
