I mean I don't really know what to say about this book because it was interesting for sure, if at times a bit predictable (especially that final plot twist). The premise seemed quite promising and interesting, but it soon became your run of the mill murder mystery which isn't a bad thing at all, but I do wish there had been a bit more mention of The Herd, which is literally the title. Overall, it was a slightly above average book, which is why I'm giving it 3.25 stars
