An editor interviewed for an article in the NY Times says there’s “a huge rise in the amount of books by stay-at-home moms writing fiction and nonfiction about that experience.”
But does it always have to have a name? You heard "dick lit" and "lad lit" a few times, but those terms have faded (full disclosure: maybe because that particular genre didn't sell). But it does seem like books by women tend to be labeled more than books by men.
I agree with Jennifer Weiner. The article says that she resents that women writing domestic dramas are categorized in ways that male writers aren’t. “My feeling about my own work is, I could be writing ‘The Aeneid’ and they would still have to call it chick lit or mommy lit or menopausal old hag lit.” She paused. “Crone lit — is that what’s coming next?”
