Actually really good. Cas, somewhat ghostbuster, travels around to somewhat "help" ghosts cross over to the other side. Takes up this Anna case after what he heard she could do. In a way ends maturing, finally made some friends, and fell in love, who just happened to be Anna. He's stil dealing with his father death, still plotting revenge against the demon that killed him. Wasn't surprised at his decision at the end about what's going to happen to him.
Could have done w/out the cat scene, it was out there.
I will actually read the sequel and see where this journey takes Cas/Anna.
