This is an interesting and thought provoking novel, with solid theological arguments and realistic objections. The characters are interesting and likable; the dialogue is thoughtful. Overall, I enjoyed it. I did, however find it a bit unsatisfying as it just sort of "ends" without any climax or resolution. I want to know more about these characters and how things turn out for them. I was also waiting for all the excellent doctrinal build up to finally reveal the Gospel, but it didn't get that far. I read that they were working on a sequel, but that was some years ago, and there is still no sign of it.
