Frequently, an author gets "orphaned" at a publisher. What this means is that an editor buys their book, then ends up getting fired, promoted, or transferred to a different job somewhere else. It sucks for the author because suddenly the person who liked your book enough to buy it isn't around to help you edit and promote it.
Patrick RothfussA lot of new writers assume you have to know the where the story is going and that it flows out as molten gold. But really, sometimes you think you are going to one place, but then you decide that is dumb idea. Then you go somewhere else and it is a worse idea. But then you switch again and you might have a beautiful accident.
