I laughed so MANY times at the conversations between Lucy and her grandma. I could've made almost all of their conversations some of my favorite quotes. It's a sort of witty, sarcastic humor. Not only is the book incredibly comical, but it is REALLY good as an audiobook. It might be the BEST audiobook version I've ever listened to (and I've listened to hundreds of audiobooks). It honestly sounds like a true podcast, musical intro and all. But the off podcast conversations and storyline are just as good. These narrators really bring life to the characters. It keeps you interested throughout the entire book, wondering how things will come together and who is the true killer. If you love true crime, podcasts, auidiobooks, and suspenseful psychological thrillers, you will love this book!
