I found this disappointingly slow going. There’s nothing particularly wrong with the book, it just didn’t grab me enough to get through it quickly. Esme is quite passive for a protagonist. Things happen around her and to her. It’s a bit depressing. 
The words are the real star of the story. I enjoyed the premise that there’s a gender bias in these original dictionaries and the process of collecting the women’s words and defining them was really interesting. The story could have benefited from more of that.
