Query: The worst edited book I've ever read

I just finished reading "Thief of Hearts" & was absolutely appalled at the grammatical errors & the poor English used in her writing. I have never felt compelled to contact a publishing company before to complain about one of their books however I could not let this one slip by. Today I sent an email to Publish America letting them know what I think about their quality of editing. Every page had grammatical errors & as a result it takes so much away from the actual content of the book. I also found the characters to have no depth whatsoever so I don't understand how some of the other readers can rave about the interesting characters. I can't believe the number of people who gave this book rave reviews! It is by far the worst book I have ever read!
