This book is part of the Midnight Coven Universe. It is a novella and can be read as a stand alone. I enjoyed this book. I will be honest and tell you that I have read only one other book in this universe. But you really don’t have to read them all. I don’t feel like I missed out on anything. This book is absolutely a stand alone. It took me a little bit to get into because the storyline skipped from present to 3-5 years ago and that was a little bit hard to follow until I got the hang of it. Hayden is a tortured knight who is ordered to kill Katherine.. only he can’t kill her. Hayden fights to keep her safe and they grow close and fall in love. There is so much more to this story. I had a hard time with the timeline jumping around but it honestly gave us back story and made a short novella seem longer and filled with more story. If you love hot vampire romances, I highly recommend this book.
