This novel was a very dark and realistic take on being held hostage by a hostile foreign country.
Luckily the couple and their captain of their ship were privileged rich people who had connections to help them out of the hostile situation. I would hate to see what would happen if the captured hostages were regular people. Not to make light of their situation, it was horrible what happened to them and I am glad they are okay.
I'm glad that there was no prejudice against Muslims and Iranians in general as far as I was aware of.
