According to the description, which says it's for people 50+, I'm about a decade short of being the intended audience, but I still found this to be an enjoyable book. This was the first book in the series that I've read, but I'd consider reading the previous books.
To me, the mark of a really good murder mystery novel is when think you have things figured out several times throughout the story. There were at least three characters who at one point I was convinced were the murders. Then I'd change my mind a little later in the story. I did not expect the ending we got, although it was a good resolution. Normally, I don't like open-ended endings, but there are a few things left unresolved at the end. I liked the uncertainty.
As a warning to readers, there are a lot of characters. I didn't keep them all straight all of the time. Once some of them start getting killed off, you get some cops and other characters, so the amount of characters never really slows down. If, like me, you get a bit confused when there are a lot of characters, I'd suggest focusing mostly on the main characters.
This book does have a few editing errors, mostly the wrong word, such as "he" instead of "the." There were enough of them that it was noticeable, but there weren't so many that it was unreadable or distracting.
The book description says, "By the way, this book doesn’t have cursing, not even amusing cursing." I'm not sure if that was meant to be funny or if I'm missing something. There are several swear words in the book, especially in the jokes at the beginning of the chapters. As for sexual content and violence, that's more behind-the-scenes than on the actual pages. A few of the jokes at the beginning of the chapters got a little too dirty for my taste.
I won this in a Goodreads Giveaway, and I provided a voluntary review.
