Jennifer L. Armentrout is one of my favorite authors, it's no secret. As soon as I read the description, I immediately added it to my "To Read" list because I'm pretty much guaranteed to like it, if not love it haha. While this wasn't one of my favorites of Ms. Armentrout, I still really enjoyed reading it. I was able to connect to Ember, and you could feel the love she had for her sister. The writing is superb, and the storyline, while a little slow in the beginning, was great! 
 I loved reading about Ember and Hayden's relationship. Their relationship grew over time, it wasn't "insta-love," which I really appreciated. However, the reason I couldn't give this book 5 stars is because I didn't like their relationship as much as the relationships in her other books. There was just something missing for me, but I just can't put my finger on it. 
 I highly recommend this book for fans of Jennifer Armentrout because it will not disappoint. I was surprised to learn that it was a stand-alone novel because I think that it has the potential to be a series. It wasn't predictable, and full of mystery. I can't wait to read more from Ms. Armentrout, as I know it will be fantastic :)
