What It All Means..... . As David Catrow tells us in his introduction, "...For me, the Constitution is a kind of how-to book, showing us ways to have happiness, safety, and comfort...", and he uses his immeasurable talents as an artist and cartoonist to teach an inspirational and unforgettable lesson that is sure to open interesting discussions at home and school. Following a glossary of what the actual words in the Preamble of the Constitution mean, (e.g. "IN ORDER TO FORM A MORE PERFECT UNION: To come together and make things better for everyone who lives in our country. INSURE DOMESTIC TRANQUILITY: To make sure we can all have a nice life and get along with one another. TO OURSELVES AND OUR POSTERITY: For kids, parents, other grown-ups, and all the people born in our country after we are."), Mr Catrow details the meaning of these important ideals, phrase by phrase, using his marvelously bold and busy cartoon illustrations. Each two page spread is a clever feast for the eyes, rich in engaging details, manic energy, and droll humor. Perfect for youngsters 8-12, We The Kids is a witty and memorable treasure, and one of the real winners of 2002 that shouldn't be missed

Ex Output:
POS

Formulaic . I was bored - really bored, which is why I picked this book to read from the free book trade shelves at work. It has a good basic story but is so formulaic that I was able to predict the ending after the second or third chapter. Being a medical professional, it was difficult to read about procedures that are outdated now and remember when they were cutting edge. Perhaps it's also a bit scary to remember those I've worked with in the past who have had the same narcissistic outlooks. I think I'll pass up the other books by Dr. Cook that I have not read as of yet. This is the second one of his that, in my opinion, bombed miserably

Ex Output:
NEG

Refund Requested . I have read all four of Sarah Vowell's books. I believe that is all of them. I thoroughly enjoyed three of them and would strongly recommend them. With for Radio On, her first book, she seems to be in a different place. Radio On is a diary of Sarah listening to the radio. Although the concept is interesting, the result is a lot of very short entries in which there is little opportunity to develop anything. But the real reason I didn't like Radio On is because of Sarah's perspective at that time. She is a very critical person in this book. Nirvana is the greatest band ever, and The Grateful Dead is worthless. Whether it is music, politics, or a variety of other topics, you get the clear impression that her opinion is right and any others are wrong. Radio On is a very mean and negative view of life and our world. The worst case scenario, though, is someone reads Radio On first and doesn't read Sarah Vowell's other books. That would be huge mistake
