As a science nerd, hearing that DNA testing could be a plot device in this book was intriguing. However, I was just not drawn in from this preview at all. The characters, especially the male ones we've been introduced to so far, come across as extremely unlikable, and that's not usually something I'm very fond of. This preview seemed to work for so many others, so this is strictly personal preference. I hope they enjoy reading it, it's just not my thing.
