I haven't read it, Mem. I mostly agree with Tina, though, in that we're not born resilient, but are given resilience, or not, as the case may be. Having said that, though, epigenetics does play a part, and some kids are born with a higher threshold of tolerance to stress than other kids. But that's given to them by their parents, so, we're back to resilience being given to you.
I think one way to rate books is to indicate whether they're informed by ACEs science or not. This one doesn't look to be, but it may have some useful info in the protective factors chapter.
