This you should probably go to if you've already at least read the first book in that series. It contains a link to the flock's (You'll know what "The Flock" is if you've read the book(s)) weblog and the official fan forum, which includes roleplaying, and more. I'm not a member on that forum, but I'm thinking about it...
Edit: I just was looking around there, there is laready a Balto fan there! It is a moderator there, and the mod's name is Aleu!
BTW, read the books, or at least the first one before you read the weblogs. You probably won't know what they're talking about if you haven't.
