Breathe the Sky isn't just a romance. It's also a journey of healing for two people who suffered at the hands of abusers, explicitly outlining in the text the tactics those who abuse use and that they're wrong. Mari and Jack are allowed to be imperfect as they find safety and comfort with each other, working to heal wounds caused by people they loved. Their trauma is handled with care and the lasting message is no matter what someone may have led you to believe you are worthy of love, no matter the form it comes in.
