Recommendations for dating books?

[Sempiternity]

I have a friend that is 35, good looking guy, and on the spiritual path, but utterly clueless when it comes to women and dating. I give him advice, but he could really benefit from some more formal education on the subject. Any books recommendations that I could buy for him as a gift that could get him more effective in the modern dating world (especially online dating, as that's pretty much what it's been reduced to in today's pandemic world). Any suggestions is greatly appreciated.
