In a letter written to a young fan, C. S. Lewis stated that Susan's story was not finished. The Christian significance of Susan's character has been much discussed. Aside from her role together with Lucy paralleling the women in the gospel who first find the risen King, Lewis may have intended her to represent the good seeds which are "choked by thorns" in the parable of the sower from the Gospel of Matthew. It is also quite likely, that Lewis may have intended to keep Susan for a post-Narnia story, about redemption, but died before writing it, as he had written to his young fans that Susan's story was not finished.
