Books about “bad” moms that are just not maternal

I’m looking for books that have mothers that not exactly great mothers to their children. But they are fine with it. Like they are not abusive parents or anything they just didn’t get that maternal gene. I feel like a lot of society once a woman becomes a mother that’s all they are and that is what dictates if they are good person or not by how much they apparently love their child instead of other things. i guess i am looking for a book that a woman becomes a mother but doesn’t put her child first in her life? again not abusive moms.
