This book is very poorly written. I'm glad this is the end to the series. I only got about 100 pages into this and I had to stop as the story just kept getting drawn out and drawn out. There are so many characters to keep track of that you get confused about who is who, who did what, and who is doing what in the story. I was to the point to where I didn't even care about the who, what, where, when, how, I just wanted the story to end.
As for this being a Christian book, I find it to be an odd, almost vulgar book. I don't suggest reading any books by this author. The first book in the series (which I'm not even sure it matters if you read book 1 to understand this one..because you won't understand it anyways) was also poorly done, but a bit more readable.
Revisiting one of my favorite series was awesome. The characters are more developed and the story just "sucks" a person in. I'm not sure if there's a third book being published, but I hope there is!
