There are few books that seem to mix two genres, or traverse the fine line between the two. I don’t mind that, as long as they do justice to both. I’ve read romantic thrillers, comical murder mysteries etc. The blurb of this book promised a mix of horror and thriller, while throwing in an aspect that isn’t explored in IWE (or at least, not to my knowledge) — the undead or zombies. It also helped that I had heard about the author from friends as a writer who was established in the genre of horror.
