Query: Stupid book

The book came on time in great condition but it's one of the worst books i've ever read. A friend actually lent it to me and it took me so long to read (b/c it's soo boring and hard to read b/c it's so poorly written) that the book actually got spilled on and ruined so I had to purchase him a replacement. This book was very cheap which is great.
