Kushner's fine story in current New Yorker w/ a twist at the end

Rachel Kushner has a terrific story, Stanville, in current New Yorker double issue, a close look at life inside a max-security eponymous prison in California Central Valley, story told in alternating points of view, overlapping, of two people: a young man, somewhat of an idealist and devotee of Thoreau, who has chosen a career or teaching prison inmates and preparing them for their GED exam, choosing to work in a women's prison because he thought it would be somewhat less dangerous than a men's, and one of the inmates, Romy, a lifer, an attractive black woman who is among the most intelligent - scorns the GED prep as she already has a h.s. diploma and pushes the teacher, Hauser, to provide her w/ more challenging assignments. The story peripherally deals w/ the hardships and dangers of prison life, but is mostly about the boredom of the life and the contempt that all the employees feel for the prisoners: One harrowing episode involves a woman on death row spending hours piecing together some  kind of blanket or poncho, which ultimately gets thrown in the trash. You can see the arc of the story develop as Hauser becomes attracted to and gradually even obsessed w/ Romy - and how he resists his obsession. He seems to be leading a completely isolate life in a one-room cabin up in the mountains; he calls it his Thoreau year; a friend whom he writes to calls it his Kaczynski (Unabomber) year. You pick. In any event, Hauser resists the urge to Google Romy - he knows  a few salient facts about her life, but does not know what sent her to prison - protocol is that one never asks this question directly - until his year of service is completed. I was pleased to see that one of the books Hauser recommends to Romy is Pick-up, set in SF (where she is from); they both note the surprise at the ending, which I won't give away; similarly, Stanville has a bit of a surprise ending as well, esp is you follow Hauser's lead and do your own Google search. This was a really fine and engaging piece - not sure if it's part of a longer work, bu it seems Kushner is onto a story line and setting that has more possibilities - which of course might mean it's a perfect place to call this a completed short story and just stop.
