[EX Q]: I was extremely disappointed with the fabric and color when it came. It is obvious that it is of poor quality but I guess you get what you paid for 10 bucks.The zipper of the plastic cover of one set was broken.I bought 2 queen sheets and I wanted to return both purchases if only I did not have to pay for shipping.Do not buy this!!!! You will regret it.
[EX A]: Negative

[EX Q]: I've read several other Deborah Smith books. In my opinion Blue Willow was the best. Sweet Hush was by far the corniest book, I've read in a long time. The phrase "Sweet Hush" must have been at used at least 100 times in the book. The main character "Hush" was predictable and one dimentional. If you enjoy Deborah Smith books, I would skip this one.
[EX A]: Negative

[EX Q]: This book did not help me with my economics class. Even though I passed the course with a B. This book reads more like a novel and really does not simplify economics at all. I work better with definitions and examples and this book gives none.
[EX A]:
Negative
