Kingdom of War (Kingdom Journals Volume 4) by Tricia Copeland
This is the first book that I have read in this series. It can be read as a stand-alone but for me personally, I would have liked to have read the others first. I like knowing everything and it would have been good to know the history between the main characters and their stories. I liked how the author intertwined the Bible and the history of the angels with the witches. I found it added more depth to the story. I found this book to be quite original and entertaining. I will definitely be reading the preceding parts to this series.
