This book was a quick, easy read, littered with pop-culture references (a couple of which are good enough I won't spoil 'em), and reminded me, more than anything else, of the old Wild Cards series edited by a then-far-less-famous George R. R. Martin (Find those in Ppb if you can, they're worth it!). In the world's internal mythology I found echoes of Wild Cards' Aces and Jokers, although Pandemonium is a different sort of book, a bit more angsty. Basic premise: in the 1950s, like the book blurb says, Demons appeared in the world, possessing people and wreaking havoc... The rest of it, you'll have to discover for yourself. The main ch. is angsty, and bit on the angry-young-man side of things, but still readable. The writing is acceptable, with flashes of occasional brilliance. Plus, for Philip K. Dick fans, not only does PKD make several appearances (As himself... sort of) but a few key parts of his philosophy are integral to the workings of Pandemonium. Worth checking out. Got my copy used in paperback, finished it in like two, three days, so it's a quick read, and an enjoyable one.
