Christmas in July

From publisher blurb: When the north winds blow, Bringing with them ice and snow, If Midsummer’s weather’s numbing, Then know that Fimbulwinter’s coming. Christmas in July is a self-contained adventure, set at the height of summer. As well as containing material that can be adapted for more conventional games of the ’TWAS RPG, this book also introduces new monsters to the game, and four new Player Characters.
