Chicago

 From the signing/Q&A in Chicago, August 8.
Q: Where is your next series going to be set in?
Stephenie : Are you talking about The Host?
Q: Yes.
S: Alright. My next series, well right now it's a stand alone, we'll see if I can stay away from it and leave it that way. It comes out in May, it's called The Host. It's set ... mostly in the South West, a little bit--actually a little tiny bit in Chicago, the suburbs of Chicago. And there's the little bit of San Diego and then the rest of it, for the most part in the South West.
