Full of ideas, some really cool, but the mix of Charlie Stross and Jane Smiley didn't quite gel for me. I think she may have built the right world and found the wrong story to tell in it -- in a world that's plagued with so many really terrible problems, it just constantly rings odd to be focused on a girl from a well-heeled political family in her freshman year at a fancy liberal arts college (though at least it is in space). It's a weird enough approach that I kind of want to recommend it, but the execution starts rough and doesn't consistently improve.

It did win the 2012 Campbell award for best novel, though, so somebody's mileage varied.
