Word choices in books

Right now I am ready a series - and they are using one word over and over again - and it’s making me cringe.

The word is fucktard.

Once or twice fine, but this is being used heavily.

What do you do when authors continue to use a word that annoys you? What are some examples of it?

Edit: once or twice is not fine. I always thought it was a slur - and the comments show me that is true!
