Good advice through a very specific lense.

So the science in it is good, as far as my knowledge goes, but it's applied through the lense of her experiences, which are not very intersectional.

The author is a Christian mother, and talks about that lot. When it comes to her advice it is always applied through the lense of being safe, i.e. not at risk of being attacked, and from a place of power in a relationship. The biggest fears she talks about are not being picked first for a sports team or her work being criticized.

If you are safe and in a position of explicit or implicit power I think this is a good book to read. If you are on the other side this book has a lot less to offer you.
