There are quite a few very nice UI touches. I think the bit about the author (authors?) being 17 is relevant because it seems like they put a lot of thought about how to represent a book on the web and came up with some new conventions, just like you'd expect from a new generation. The chapter navigation widget at the top for example, where the previous and next chapters are slightly opaque. Haven't seen that before.

Such a tiny and, in hindsight, obvious detail. It's surprisingly pleasant. When I noticed that, I knew I had a passion project in front of me.
