Authorized by the folks making his spinoff series…
(cover art not final)
Supposedly this is going to straddle a behind-the-scenes look at the character’s Doctor Who origins and his revival in the new show, and yet also have aimed-more-at-the-kids stuff like you’d expect from one of the older Doctor Who Annuals. (What a mix!) It’ll be out sometime in 2012. No idea who the writers will be, but I expect the name of Paul Tams (co-executive producer of the K9 series) will be on the cover somewhere.
As the series isn’t shown here, I don’t know how easy or how hard it’ll be to find.
