This book was very different from the rest of the books in the series. In this book we have a various amount of journal entries and little snippets of what happens throughout the series. You will want to have read the previous books if you want to read this one. I will say make sure that you want to read this one here, if reading little journal entries of a different POV isn't for you, then you can easily move on from it if you want to. I have loved the journey that we see of Damien and Nikki and it was very fascinating to see their journey into this one here and seeing them find their way together through the various conflicts that they face together. This was my least favorite of the series though. I probably would have preferred if the author had this as a prequel and read it along with the series instead of it being at the very end of the series. But that is just my personal take on it. I would recommend reading this along with the books if you can.
