Most everything by Leil Lowndes is great IMHO. She helps you understand body language, which is a huge key to success. Most people telegraph their feelings with body language so you can pretty easily recognize who wants to talk and why doesn't. She also has a great sense of humor. Her books are very 90s/00s which might bother some people, hence this warning. Specifically she generalizes quite a bit based on sex/gender. Not in an exclusive way, but if you're somebody who feels strongly for example that there is no biological difference between the sexes, then you might have a hard time with her books.

"How to talk to anyone" would be my first recommendation.
