Seriously? Why no mention of either in this book?
I presume you mean 12M?
BC: Possibly because things are too unsettled, and everyone is on alert; even the
mortals are becoming supernatural-savvy!!! This isn't the best environment to try for passing unnoticed...
Possibly because they don't have any active targets/opportunities.
Possibly they
are there, but Harry's too distracted and off-his-game; and since the POV character doesn't notice them, we don't either... but Kravos having gotten some up-powered spellwork to operate in Dresden's area (if that was a BC op) might get us speculating about how Kravos' Book of Shadows ended up with Bock...??!?
GC: Because they mostly are a counter-BC op. No sign of BC = not seeing GC.
