Pretty good! I'm not writing home about it or anything, but it's a lovely fantasy and competently explores the feelings of trespass, uncertainty, and finally understanding that we work through in the process of realizing we're trans.

It's not a long read, so if you're on the fence about it and you can get it for free from your library or Anna's Archive, I'd say give it a shot! I had a good time and you may well too!
