shan- i was thinking about that as i read the book last night, and so far i think its texas tech. i dont know much about their greek community, granted, but i do know they have houses and a larger number of organizations.
im just assuming she's using a texas school, because there are a lot here that are not as "southern" about sororities as most other southern states, and because a lot of the sources when she does site an actual NPC sorority she sites schools or women in texas.
but now that i think on it more, i think it may also be UT... because greek life is decently big, but not the end all of everything there, and because of its size, etc.
i just think its in texas
ETA to say that i dont think the 18 sororities count is true in her book, that its one of the changed elements, because if it were true it'd be pretty easy to find all the schools with 18 sororities and figure it out. i mean, there aren't THAT many universities with 18 npcs in the country...
