This audiobook really dug into addiction, along with triggers, treatments, and the fact that it is a lifelong disease. It is done very respectfully and in a manner that was easily understandable for a disease that sometimes is hard to understand. The author also touched on adult ADHD which mostly stays out of the light. Along with all of these items, the storyline showed different problems the characters can have from these diagnosises. I could listen to the narrator all day 🤫. All around, this is one of my favorites in this series.
