Since PFD imploded last year I think their genre agents were part of the mass exodus to United Agents
At any rate, Robery Kirby, (who represents Joe Abercrombie, John Clute, Alasdiar Reynolds, Christopher Priest and more) is with UA, so they should be added to the list.
They do take email subs but have some specific requirements, so check their guidelines (of course you will
)
