Query: This isn't really a book

First of all the content is, well, okay. But don't expect this to be what you expect a book to . It is really really thin-- only 63 pages long. Most magazines are thicker. When I opened the box, I thought it was empty. The book was so thin I didn't notice it was under the invoice ! Fair enough;one might argue that you can say a lot in 63 pages. But wait a minute! That's not all. Clearly half of the pages have huge blank spaces...for you to fill the blanks with your exercises, you see.It is,after all, a workbook. Then there are completely empty pages in between chapters that are counted within the 63 pages. But what makes this so unforgiveable is that most the pages that are full have huge margins to the sides, top, and bottom. Some people might find the content good, but you can get a lot more for your money elsewhere in my opinion.
