I am currently reading my way through a long list of science fiction and fantasy titles. (http://www.npr.org/2011/08/07/138938145/science-fiction-and-fantasy-finalists if you are interested in the list).
This is a really weird mix of poker and tarot cards, with the cards causing threatening things to happen.
I'm a hundred pages in and I still don't have any idea what exactly is happening (but that's parr for the course with Powers' writing & me).
But it certainly isn't boring!
