Just a quick update to indicate that I've stuck Jam on the sidebar over there to the right, if your eyes can bear to be separated from this sentence long enough to glance at it. The book's now available to preorder from TFAW.com. Also Amazon and Amazon.co.uk, but they haven't got the box art set up yet, lazy buggers.
Also, since someone asked, no, Jam won't be out by the time of the Escapist Expo. You see, the Expo is in September, and Jam comes out in October, and October is the month that comes after September. Sorry about that.
