It's damned hard for any woman to get into the canon, and yes, domesticity doesn't help - apparently small-scale stuff about small lifes. The fact that it's also about universal human experience gets missed.
And her style
is very understated - absolutely beautiful, but Elizabeth Bowen, say, is more radical to read, as well as more wide-ranging in setting and stuff (says Emma, who's only just read her first Elizabeth Taylor
): you're more conscious of the daring of Bowen, I suppose, which maybe gets you more readily admitted to the self-conscious end of the canon which is measured by your contribution to the progress of literature, if you like.
