Query: The most unprofessionally edited book I've ever seen....

I thought this book sounded interesting, so I bought it. Unfortunately, I was sorely disapointed. The first two pages were unreadable - the grammar was horrible, as was the spelling. It left a bad taste in my mouth, especially after I've read books by BL Miller and Melissa Good. This writer needs to go back to 8th grade English and take a refresher course.
