Is Being a Stepmom So Hard? I Became a Star by Taking Down Scumbags

Are There Any Books With a Highly Intelligent, Meticulous Heroine Who Plans Every Move?

Looking for books similar to "In the 1960s, I Became the Scheming Female Lead's Stepping Stone". The female lead can suffer, but she must always get revenge. Good writing would be nice, but isn't essential. I just hope the golden finger isn't too overpowered; a little female-lead luck is fine. I still prefer smart female leads.
