I loved the first story in this series, but I think I enjoyed this one even more. This story gives us a lot more insight into the boys; who they are, how they live and how they relate to each other. The case part of the story was great. I thought the mirror was interesting and I was dying to see what Sam and Dean saw in it. (I wasn't disappointed.) But to me, the best part of the story was the insight gained about the relationship between Sam and Dean. Their relationship seems very strong and beautiful. They fit together perfectly.

Is there any chance that Sam will get his ability to change shape back in future installments (if there are any)? It seems a bit sad that he's stuck in human form all the time.
