Was at the bookstore yesterday looking for a copy of Saturn's Children, but didn't find it. The closest thing was a much more recent novel by Charlie Stross, The Jennifer Morgue.
That review is a little glowing. It's a fun book, but I won't remember it in a month. It does flow fairly well. I read it pretty much at a sitting between 4pm and midnight. (Of course, at only 350 pages it's not a long book.)
Still, if the idea of James Bond meets Cthluhu with a liberal salting of self-parody sounds like your kind of fun, let me know and I can loan you my copy. You could certainly do worse.
