Yes, you're welcome to use my story in Traveler of the Mists. Don't think I'll have the time to write it myself, currently torn between the sequel to Awakening, a new story that won't leave me alone, and finals. You're welcome to write it, would be interesting to read your take on it. Feel free to ask me any questions you might have.
My last exam is on May 15, I believe, so I'll read Traveler of the Mists around then, hopefully.
And sure, I'll back it. Don't know what's going on with my book as I've not been active in critiquing, etc. though I'm not particularly concerned at the moment. I want to edit/rewrite the beginning couple chapters first.
