I found the book odd and confusing, and honestly parts were a bit disturbing, I think it went to deep in describin the evilness of the world. I haven't read the other three, I wasn't able to keep up, I am not familiar with any of his books. "Green" wasn't for me, because it was hard to follow as a first-time reader of any Dekker book. I read that you could read this first, since it is the first and last of the series, but I don't find that to be true since he referred to the other books. I don't think I'll be reading the others, there are many other books that I plan to read.
