The first part of A Case of Conscience was excellent. It flowed great, there were some great questions pondered, and I really enjoyed it. Until the second part of the story came along. It felt added on and if I remember correctly, the first part was a short story and the second part was added to create the novel. If I was to rate the first part, it would be four stars but that second half was so messy, totally added for word count. It just really sucks because this book had so much potential.
