It's a mix of memoir and interviews she did with other people, about the issue of depression within the context of being a Latter-day Saint. My family has a lot of experience with mental health issues and neuro-divergence, so there really wasn't anything new for me.
The only thing that was a new insight wasn't even new - just a reminder to keep an eye on younger women in my circles of influence when they are pregnant, and to let them know clearly that 1. "postpartum depression" can also happen DURING pregnancy (because no one seems to know that until you actually go through it, which I did, and it's kind of scary when you don't know what's happening), and 2. that I am on standby for assistance should they experience any kind of depression during or after pregnancy.
