This is the longest and best story so far.
Kress‘ strength is to put believable characters into flawed settings. In this case, the protagonist suffers of Fatal Familial Insomnia. Medical researchers under a libertarian government experiment with her by directly manipulating her brain using some fancy technology.
I constantly feared some mixture of Flowers for Algernon (curing brain deficits) andBeggars in Spain (sleepless culture) but it developed quite differently:
We follow the young female through her Mississippi setting, family drawbacks and fight to do the right thing.
It brings up questions about the impact and ethics of medical research.
Half a point off because of some large info-dumps.
The story is rightfully included in The Year’s Best Science Fiction: Thirty-First Annual Collection.
