So, reading the newsletter today, I noticed FPW mentioning that they were working on turning 
Masque, the second book he wrote with Matthew J. Costello, into a game. As I just finished reading 
Masque last night, this piqued my interest.
As much as I want to know about the game (is it a sequel? A direct continuation? A retelling? TELL ME TELL ME TELL ME!), I wanted to ask more generally about the Wilson-Costello books. There were only two, as far as I can tell - 
Mirage and 
Masque - my copy of 
Mirage mentions an upcoming book called 
DNA Wars, but I'm assuming that became 
Masque.
First off, why are these so neglected, even around here? Do they have a bad reputation or something? I read both recently and really enjoyed them both. Sure, they have a couple of flaws (more 
Mirage than 
Masque), but they're very minor, and few books 
don't have some flaw. Besides, we can just assume those are Costello's faults, since he's not here to defend himself 

.
Also, I was wondering how that partnership came about, and whether it will ever resume. 
Masque definitely feels like the two styles meshed a lot better, and the result is pretty satisfying - why no more? Does anyone know? Or is the game a return to that?
