‘Mega-novels’ are not a marketing wheeze, but a necessarily giant scaffolding for vast imaginative reach
Recently Damien Walter wrote about the tyranny of fantasy serial mega-novels. He suggested that fantasy novels now tend toward the enormous because of market forces — because everybody in the publishing and television industries is looking for the next Game of Thrones,anda new author who can open a factory of imagination that will lead to commercial success. I don’t think that’s the reason behind the size or format of fantasy books at all.
Last year, I was teaching on a short fiction course and agreed with the convenor that I’d do genre fiction while he covered high literary, New Yorker-style stuff. But although I read truckloads of fantasy, and write it, it was very difficult to find fantasy short stories that don’t lean in some way on an existing corpus of novels. There’s a very good reason for that, and it’s nothing to do with market forces – and everything to do with the requirements of the genre itself.
