I'd already read Iron Sunrise, which is the sequel to this, and I loved it. I had great expectations of this. It didn't disappoint, but I had a similar experience to reading Peter F. Hamilton's Mindstar trilogy, which I happened to read in reverse order: there's a sense of slight disappointment since they'd had worked so much better in the right order. Oh, well. My fault. This was still great.
There's more (less? this is the first book...) of Martin, Rachel and Herman. Rachel gets to be cooler here, I think, but the girl (I forget her name) made a better protagonist than Martin. Plus, the Remastered from Iron Sunrise were just so much scarier than the far-more-abstract Festival here.
This is the latest collection in Miek Carey's on-going Lucifer series, featuring the character from Gaiman's Sandman series.
It's been a while since I read it, and honestly, I can't really remember that much about it. Lucifer has that effect on me: it's always very, very good, and I probably don't understand it all that much. But Carey writes Lucifer, as a vastly superhuman intelligence, so well, that it's great regardless.
This, Carey says, is a character who sees the entire universe as tools to be used. For all Lucifer's suave sophistication, every now and then Carey has to remind his readers that Lucifer is a monster: he'd burn up entire planets just to light a cigarette, if it suited his purpose - or if he didn't imagine that he'd find said planet useful in the future.
From what I recall of this one, we have more Fy Presto, still trying to get rid of her cards, and more Elaine Belloc - suffering a serious case of indigestion from acquiring her father's demi-urge. Her father, incidentally, is the Morningstar's younger brother, Michael.
Basically, Carey's taking Milton further: Lucifer has his own Creation to rule, and given what he is, this is how Carey sees him doing it. Here, Lucifer isn't Milton's evil monster, though - he's just disinterested in servitude.
If you liked Sandman, you should try this. Except, if you liked Sandman, you probably already have.
