Christmas shopping ideas
If it's steampunk action and adventure that they're into, try my Pax Britannia books.
If they love gamebooks and fantasy adventures, try my Fighting Fantasy gamebooks.
If it's Doctor Who or Star Wars, try these, and remember that you can have a Clone Wars story, written by me, personalised.
If it's non-fiction they enjoy, try Match Wits with the Kids, or one of my Miscellanies.
And if its the grim darkness of the far future where there is only war, or the grim darkness of a quasi-Medieval world that gets them buzzing, then try one of my Black Library novels.
