Since Jo Walton undoubtedly has a few fans here this announcement may be 
of interest:

As of a few minutes ago _Forgotten Futures X: The Tooth And Claw Role 
Playing Game_ is on line. Contents include complete rules for dragon 
adventurers, a detailed sourcebook for Jo Walton's World Fantasy 
Award-winning novel, and adventures. There are HTML and PDF versions, 
and bonus contents include three chapters of the unfinished sequel to 
_Tooth and Claw_, _Those Who Favor Fire_, a cutout paddle steamer, and 
character record forms in several formats.

There will be another Forgotten Futures release within the next few 
weeks. _The Forgotten Futures Compendium_ is a collection of material 
that for one reason or another hasn't previously been included in one of 
the main game releases. It includes a _Flatland RPG_ crossover _The 
League of Extraordinary Geometers_ and Alex Stewart's wonderful African 
adventure _Curse of the Leopardmen_, plus a collection of Victorian and 
Edwardian advertisements and adventure ideas.
