Bookthreads : Is Throne of Glass Romantasy? I didn’t think it was (having read the first four) but rather more fantasy romance. But now I’ve seen it referred to as Romantasy on a couple of different sites. I’m not very well read in the genre and I’m trying to figure out the dividing line for a critique group I’m in where one of our members is writing what I’d consider fantasy romance. Or maybe the genre boundaries are fairly blurry?
