As for the "The Cold One" sequel question...the sequel has not been written, and from what I understand, never will be. There are some adult books to look forward to soon, though (yay!). I, personally, loved "The Blind Mirror."
I also have a question. While I like to write, I have never actually written a "fanfic" before. Is that all that this community is meant to contain, or can well-read fans who just write fiction containing their own characters remain as well?
I love the idea of a Christopher Pike community, but I don't know that I particularly want to write a story containing any of his characters, feeling that I could not do them justice. While I like to write, I am not a very good writer. It would feel akin to blasphemy to completely change his characters, and I feel that my frustration at being able to accurately capture his characters' essence would reach intolerable levels.
So...I hope that the creator of this community is open to fans who don't necessarily write fan-fiction.
