Mercury Rises" is a fun sort of tale of angels and demons and humans who are (mostly) acting with a piece of information while chasing around the world trying to stop (or start) the apocalypse."
Fiction is "mind candy" for me most of the time - meant to be fun and tasty without a whole lot of substance. This fits that bill.
Well written, characters were well defined (with some books it's hard to keep track and this book was nice in that regard)
I'm planning on reading more in this series.
