Well at least she made a good decision in the end. I am sorry but everyones life gets a little boring every now and then that is no reason to have an affair. Her husband treats her good and loves her in his own way but that isn't enough for her. She has to go and find someone to "light her fire". I am not a big fan of adultery.
Taking Flight was alright. Mother is unhappy with her life/husband, goes on a trip, meets someone, etc. etc. Really easy read; kind of generic storyline. Didn't take any "morals" away from the book itself. Just something to read if you're bored, but it's definitely not something I would read again.
