Query: Good information, but.....

I purchased this book from Amazon about a month ago to help our family prepare for a trip to Rocky Mountain National Park. It is obvious that the author knows her stuff. The book is formatted in a user friendly way, giving specific details regarding the park and its trails. (here comes the big BUT...) BUT, I was very disappointed that the book literally fell apart in my hands after using it only several times. When I buy a "guide" type book, I would hope that it would last for than a few days of use. This thing was so shoddily made that pages were falling out of the binding almost immediately after I purchased it. The book was not misused, bent, or even creased. It just looks like it was poorly made.It is unfortunate that the author's hard work is compromised by haphazard printing and binding. I would buy another book by this author, but only if it were published by a different company.
