May Sarton (whose first name I always think of as "Mary").
I would like to suggest this for bookclub, one or both, because it's short and, as far as I'm concerned, brilliant. But I reacted to it way too personally: is it really brilliant, or did it just speak to me so intimately that it must be perfect? I could deal with its not being chosen, but if it were chosen and disliked, I wouldn't want to attend the discussion, let alone host it (as each book's selector does). I might even have to explain why it is now a favorite book when I am not 70, a poet, or noticeably bisexual, and I don't know if I can do that.
One thing I can say is that I like how unafraid Sarton is to use symbolism plainly. Mrs. Stevens is an interview subject; her two interviewers drive past quarries to reach the woman they consider their quarry. One interviewer is named Hare, and both actual and metaphorical pebbles are thrown into the deep still cold quarry waters. When an interviewer asks if something were a watershed moment, all three submerge again into the conversation.
