Bests & Worsts Reviews from Amazon

I picked up this book as part of a free promo, and I was looking forward to reading it despite the many negative reviews it received. A lot of readers didn't like the main character, Madison Knight, because she is a tough, strong-willed woman. I'm the opposite, I like tough, strong-willed female characters, and so I started to read the book with an open mind. Unfortunately, the author did not handle at all well the development of Madison's character, and Madison came out looking like a one-dimensional character rather than a person the reader could relate to. In the end, I ended up disliking Madison and her manner. (Spoiler in this paragraph) The plot was okay except the "twin factor" has been done in many stories, and I knew who the killer would be even before the author revealed it. Having said this, I could live with this, too, if the writing in the story would have been good. The one thing I really found annoying was the incorrect use of grammar, especially the lack of commas where they were needed, and then, commas where they were not needed. Additionally, there were words that made no sense eg. "notta" instead of "nada"; "frickin" instead of "friggin'" or even "freakin'". There were also missed words, or words in the wrong place; and words (even whole sentences that should not have been there in the first place). This novel needs a full edit by someone who is actually a professional editor. I doubt very much whoever edited this is a real editor. One can forgive a typo or two, but the entire novel is riddled with grammatical errors, many times confusing the reader as to who is speaking, and lots of ambiguity. In short, many parts of the novel were difficult to follow. The other thing that was very distracting was the hot and cold relationship between Madison and her partner, Terry. Their dialogue and banter was so badly done (and sometimes totally inappropriate in terms of timing) that I couldn't believe it. I was also very confused when Madison said Terry was named after the casanova character in the film An Affair to Remember (this would be the part played by Cary Grant -- Nicky Ferrante); but somehow, the name Terry McKay comes up (which is the character played by Deborah Kerr). So how does this relate to Terry, the cop, if he's likened to a casanova? Nicky Ferrante was the casanova in the film, not Terry McKay. I know this is being picky, but if the author is going to confuse the reader like this, better to leave the whole thing out, or get her facts straight. Finally, the actual reaction of the characters to what was happening in the story was many times unrealistic, making the story unbelievable and shallow. It's a real pity the author made all these mistakes, and after having read the many negative reviews that repeat what I've said here (at least, I'm assuming she read them), she didn't pull the novel out of circulation and do a proper and full edit, plus develop the characters and give them some depth. She simply left the novel as is. I know an author can't please everyone, and so one or two negative reviews are always expected, but these many are definitely a sign that something is wrong, especially when a novel is badly written and full of grammatical errors. It's one thing to have negative reviews because readers didn't like the story (after all, it might not be their "cup of tea"), but it's another thing when the negative reviews allude to bad writing, bad grammar and lack of character development.
