Oh! This is beautiful. This is the kind of beautiful that makes me shake my fist and despair that I may never write anything as good. It feels abstract and a little bit removed at first, but gradually reveals its inner workings. The structure is complex, but the questions at the core are delicate and beautifully handled. It has science-fictiony parts and fantasyish parts and fairytailish parts and love stores and artificial intelligence and gods and machine dreams. I haven't read all of the Nebula novella nominees just yet, but so far this is my pick.
