My son happens to love this series which is why we are still reading it. It is an interesting story line...but theologically speaking, differs from our family's beliefs. I have to stop and tell my son that I don't agree with parts of the book and we talk about how our beliefs differ. It has Greek names which are hard for kids to read and also some difficult words to read in general- some of which I have to say "son, I don't even know what that word even means!" Kids seem to love it; I just think it is ok.
