  EDIT: added Uncanny Inhumans to essentials

There's not a lot of stuff with just Blackbolt or the Inhumans because they are pretty much background characters that rarely get their own series. I read a series called "Silent War" that dealt with them, but it was pretty mediocre. You might enjoy it, but it didn't see it as anything special. I remember "The Inhumans" being a pretty fun series, although I didn't read it all the way through. I know they characters had a semi-popular run in the 1970's that was supposed to be pretty good, but all I could find of it is the Marvel Masterworks Collection and since I haven't read any of it I can't really say whethe it's good or bad.
