The book attempts to meld several different kinds of horror into one - the "friend group who comes across an evil occult thing that draws their flaws into sharp relief", a la Stephen King, the "evil authorities working beyond human ken", a la every 1990s horror novel with a scared lady on the cover, and the "cosmic phenomenon horrifically imposes itself on earth" a la Lovecraft.  While I give it points (literally) for ambition, the melding doesn't quite make sense - there's only a nod towards the actual friendship of the group, hidden behind sarcasm and trauma (you have to let us in somehow!); the authorities are neither fully helpless (as they must be in cosmic horror) nor completely deranged (as they must be in corporate horror); the cosmic force is way too personal in its expression to be cold-hearted enough to excite fear.  Ultimately it's an ambitious muddle; but it's better than a plodding recapitulation of the tropes of the genre(s)!
