One where the main character is (preferably) a woman and is childfree?

I read mostly thrillers, psych horror, and the like. I'm getting burnt out with the main character being a mother and the children being a main driving force in the story. I get it, that's reflective of real life, but it's getting exhausting. If anyone has any suggestions of thrillers etc where the main character is not a mother (or at minimum where her children are not a focal point), that's would be fantastic.
