As an author, I don't want to just throw my work on some site and have it come back to bit me later. :) The layout looks decent, and works nicely on a phone, which is where I do a lot of reading. I like how you've handled multiple chapters. In the future, adding a search box, or maybe the ability to define tags, and search by those would be nice to see. (Thinking of the point where the site could host thousands of stories) - I hope this comes across as constrictive criticism, and not bashing :)
