I'm now officially allowed to talk about this. For the last couple of weeks I've been working on an essay for a forthcoming book about A Song of Ice and Fire. I turned in the first draft a few days ago and anticipate quite a lot of work to bring it up to standard, but I'm excited as this will be my first work published in book format (not to mention my first paid writing job ever).
The book is called Beyond the Wall and is due out in June 2012 from BenBella, as part of their Smart Pop line. The editor is novelist and former TSR fiction editor James Lowder. A full list of contributors should be available soon.
