This is a great series with a complex magical world which even has talking animals and well-known mythical creatures. The world is filled with great adventures and I'm sure nearly every child has tried to go to Narnia through their closest!
Aslan represents God as the writer was religious. However, this is not a huge part of the novels so they are still very enjoyable for people who are not religious.
I loved this series, it's a great children's series. Children may need some help reading at times due to it's older style of writing but this can be good practice as it was for me. A great series and a definite must have for anyone's, child or adult, library
