Blood Music was interesting. The concept of the story and the description of how a singularity takes place because of a biological take-off is pretty awesome. Probably the best grey goo concept I’ve read. The ending is pretty shaky; it’s clear that Bear sort of bolted it on as he bootstrapped the short story into a novel, but I don’t think that’s enough of a reason to dissuade you. Overall, it’s a pretty compelling thought exercise, and a quick enough read (barely larger than a novella) that this should probably be required reading in the canon. 7/10.
