Ghostwriter

Belfry, Dime. Those two are, if not ready, very close. They may be extracted.
Yaffenhash will be delayed, but just a bit. She could use a bit more to her character, but I suspect given a bit more time that will resolve itself without needing additional outside influence.
Puffy, hm. I feel Puffy should stay here a while longer. They haven't had quite as much time to develop as a character compared to the other three, and having a semi-familiar character to return to would ease the introduction to book two.
