This is the story of how the author talked a student out of engaging in violence with a firearm at the school where she was a guidance counselor. That's a pretty amazing thing to do. That said, the book was not for me.
The author is devoutly Christian and says that's what helped make the positive intervention, which, great. She goes on to say that God essentially trained for her entire life to be ready for that moment. This is where things start to get sticky for me. I do think all of the work, research, education, and training she did her whole life prepared her to meet the moment. That seems obvious. Saying God did that raises the obvious question of where was God when the shootings in Sandy Hook, Parkland, Uvalde, or any of the long list of places where tragedies occurred.
The author leaves out almost all of the information about the student, which is great to protect his privacy but makes the book a lot less interesting. Another, stronger, way to protect his privacy? Not writing a book about the incident.
The author works with Safe and Sound Schools, which does not promote gun control and believes that in certain cases teachers should be armed. Both stances are deeply disappointing and would seem to run counter to the lessons to be taken from the book.
Finally, and this is just conjecture, but the author is a white woman who is devoutly Christian, a gun owner, in rural Tennessee, so it seems very likely that she voted a certain way in the last election and that really rubs the wrong way. I know that's not fair since I can't be certain but I still can't escape it.
