There were some elements that I really loved about this book, and others that I did not. I'll start with the positive.
There were quite a few well-developed characters, especially Charlie and her group of friends. I loved the addition of the two older ladies as main characters, and all the shenanigans they got themselves into. I mean breaking into a hotel room and hiding in the closet - hilarious. I also liked the fact that the main characters were all women and they were all intelligent, brave, and generally bad asses. The author's writing style added humor to an otherwise non-humorous situation (murder). It was well-written and flowed easily. I didn't get bogged down or stuck anywhere.
As for the negatives, there were quite a few. The whole premise of the book was unbelievable, and the methods for solving the crime were over the top and unrealistic. It had less to do with skill than luck. It seemed like everything just happened to fall into place, and the characters just happened to be at the right place at the right time. They didn't really make any clever decisions to move the story forward. I also could have done without the love story. It wasn't well developed, it felt forced, and it just wasn't necessary. Finally, while there were characters I truly enjoyed, there were also those that annoyed the hell out of me. Charlie's mother was two-dimensional AF and she kept talking about sex. I will admit I'm a bit of a prude when it comes to sex scenes in books (they always make me a tad uncomfortable), but the mother's attempt to get her daughter to hook up with someone, anyone, just so she could have grandchildren...nah. It wasn't realistic, and it seemed very forced. It might have been forgivable if she was kooky and eccentric in other ways, but that was literally her only character trait, so I just couldn't get over it. Then there were the police officers. It was a traditional good cop/bad cop scenario. Which honestly doesn't bother me, except that the bad cop had no redeeming qualities or explanation for his laziness or his general badness. The author could have given him a back story that would have made him more believable - like he was in the middle of a contentious divorce that was weighing on his thoughts or he had a colicky baby at home that made him tired and distracted - but he had no back story. Neither officer did. And I truly wish that I had that (really for all the characters), because it would have made them more complex and interesting, and it would have helped me forgive more of the book's shortcomings.
But as it sits, this is a solid 2.5 star or 3 at the best. I gave it a 3 because I did enjoy the author's light, humorous way of writing, and Charlie was a well-developed, interesting character.
