@MiraculousMongoose Everyone's writing style is different, so don't worry about having shorter chapters! My first book on this site had about 2,000 word chapters. Not bad, but really really short to what I write for Wild Hearts, which averages about 5,000-6,000 words per chapter.
I think that a lot of the length comes from the fact that the miraculous episodes themselves are all over the place and I want to tell a consecutive story from beginning to end and as such I'm forced to add my own moments and tweak things so it makes sense.
