Query: A Darkly Fresh Perspective

I've been watching the TV show for several years and finally got around to reading the book. Definitely worth the read even if you have seen the show. What I love about this book is that the focus is mostly on Dexter's thoughts and perspectives as he tries to navigate through everyday life. Harry's Code is the set of rules by which Dexter lives and it helps him to fit in and appear normal. Watching Dexter live by his code (which some people would find horrifying) and also watching apparently "normal" people who follow the letter of the law but intentionally damage other people for personal gain is good food for thought over what makes anyone a "good person." Overall, this is great writing that is often witty and never dull.
