As per the author:
“… Jo doesn’t just become the woman she’s meant to be, she becomes the superwoman she’s meant to be. The core question that intrigued me here was this: What makes a person truly super human? The answer I came up with? Living up to your potential, even if – or, in Jo’s case, especially if – it means saving the world in the process.”
