'The Gift of Fear'
Another thread reminded me of this excellent, scary book.
It's by Gavin DeBecker, a security consultant to celebrities, heads of state, & other high-profile people who may become targets of kidnappers, stalkers, etc.
The book is geared to women;
it's about how to stay safe, how to recognize danger, etc.
I haven't read the entire book, it's just too intense, but I've read a number of chapters, & it's impressive.
If you get a chance, read it.
If you can't find it to buy, check it out at the library.
I think it's like driver's education;
it can't hurt, it's good practice, it's always better to know than to not know, & it might save you a great deal of heartache & maybe physical injury or death.
