I wonder if the editors of the puzzle take note of recent events and find ways to acknowledge things by editing the clues. I feel certain, for example, that 34D: Typical John le Carré work (SPYNOVEL) is a nod to the recent passing of the referent. But I doubt that the answer was changed in order to squeeze in the nod. I have never read any of his books.
Today's puzzle, however, is not a nod to male writers, but rather to WOMENOFLETTERS, which is then interpreted as finding women whose names are homonyms for letter names. I like that the creators found two with first names that fit the criterion, and two with last names. Of the women honored with inclusion, I am particularly fond of SAMANTHABEE and SANDRAOH.
Of the rest of the puzzle, I will note BALLET and a nice crème BRULEE. Also present are both the Greek and Roman gods of the dawn, EOS and AURORA.
I am not fond of EARWIGS, as a rule. I ask our reading public what they think of clues where the referring clue is after the referred clue. This occurs with SERIF / SANS. I'd rather they came in the opposite order, but solvers can't be choosers, only constructors.
SHEHER is very odd looking, but quite contemporary. I will finally note that "Cher or Adele" has been used quite a bit for "alto" as opposed to DIVA.
