So I was thinking... Next big campaign book: Harlequin's Revenge?
I always felt everyone's favorite painted elf should have a third book named after him 
I'm reminded of a Matt Damon quote.
"So, you're done the Borne Identity, the Borne Supremacy, and the Borne Ultimatum, will you be doing any more of these?"
"There's talk about it, but I've told them that if I do, I get to name it, and it'll be The Borne Redundancy."
