Gaiman's style really lends itself to the whole "modern myth" thing he's got going on here. As I was reading, I was pretty convinced this was going to end up being a solid 4-star book for me. 
 Then that ending happened. And just all the implications and asdfkjasdfjk. I still can't quite manage to be coherent about it. But it ruined me. So 5 stars it is.
