The reason for this is that I have found something out about myself. I don't have patience. I knew this already, but I found I don't have the patience to write a novel-length story. I can't make myself sit down and say "I'm writing this moment now". I tend to get inspiration to write about a particular thing. I can't write in a linear fashion. So, while I'm not going to delete the chapters I've written already, it's highly unlikely I will write any more. So...don't expect that I'm never going to write with the characters again, but it's going to just be scenes and moments and monologues with the characters whenever the inspiration hits.
For those of you who were waiting for more chapters, I'm really really sorry.
