What non-fiction are you working on?
Standard By Seven, a book on Blakes 7 for Classic TV Press
Lore Of Kobol: The Big Frakkin Book Of Battlestar for Hasslein books
An as-yet unannounced book for Telos about a certain set of connected shows (they prefer to keep announcements until after the manuscript is finished, rather than when it's commissioned, so they can announce them with publication dates and preorder forms and suchlike)
An as-yet unannounced book for Osprey publishing, about... um, a sort of mix of history and myth. You'll see what I mean when it's announced, which will probably be sometime this week or next
