This book (and its sequel) are annual rereads for me and every time the excitement and intensity of the battles gets me hype. The angels and demons make me laugh, cheer, and feel things so deeply (IYKYK) and their scenes are by far my favorite and the best written. I'm not sure if there is a Christian Thriller category but if so, this is a mandatory addition to tha genre. This year is the first time I'm reading the series with friends and it has definitely made this reread even more enjoyable.
