If you like Kristin Hannah (as I do), I recommend you give the book a whirl and decide for yourself.
p.s. I quite liked "Lessons in Chemistry." Lighthearted and sometimes even a little silly, but rooted in truth. A lot of women dealt with very frustrating realities during the 50s & 60s. (Had my mother been born in the 1950s instead of the 1920s, her life would have been far more interesting, happier, and fulfilling.)
Even as late as the mid 1970s, despite being over 21 and employed, to get my first CC and establish credit. my father had to co-sign the application.
My brother had no problem getting a CC, no co-signer needed. It was infuriating.
