A brilliant story and inside joke in one! 
 NPCs (Non Playing Characters) is a behind the scenes story of all that goes in a RPG (Role Playing Game) when the adventures screw up and the extras and bit players have to step in and do the job instead. 
 The whole story is a finely crafted subversion of everything you expect from a RPG. The character are interesting and make a true journey of discovery throughout the book. 
 A must-read for any RPG player!
