She gets a fairly impressive mention
here.
And in another article on the Demise of the Midlist (dooomity-dooom!) she appears again : "Nicole Aragi, the superagent-of-the-moment who brokered Jonathan Safran Foer’s handsome payday. Aragi embodies the blockbuster mentality better than most. She claims not to bother with midlist clients and takes on at most one or two new authors a year, and then only the superhot (she also represents Junot Díaz). Winning Aragi’s approval in itself is a benediction of sorts."
She's also one of the agents interviewed
here, which might give an idea of what she would be like to work with.
All of which is moot if she's closed to queries, though.
