I have never read a book by Tana French and the first time I saw her name was in the Eagerly Awaited August Books where both Dabney and Lynn indicate that they are looking forward to her new release Broken Harbor. Then while surfing the Web, I came across her name again. She wrote an article for Publishers Weekly outlining her writing tips.
A few of them didn’t resonate, but this one did:
There’s no such thing as ‘men’ or ‘women’. There’s only the individual character you’re writing. One guy emailed me asking me how to write women, and I couldn’t answer, because I had no idea which woman he meant: me? Eleanor of Aquitaine? Lady Gaga? If you’re thinking of ‘men’ or ‘women’ as a monolithic group defined primarily by their sex, then you’re not thinking of them as individuals; so your character isn’t going to come out as an individual, but as a collection of stereotypes. Sure, there are differences between men and women on average – but you’re writing an individual, not an average. If your individual character is chatty on the phone or refuses to ask for directions, that needs to be because of who he or she is, not because of what he or she is. Write the person, not the genitalia.
