Hey All, I have recently been reading a lot of cool books that I find create AWESOME discussion with girls. "Blink" specifically... although the author has a few other good ones.
It is all psychology / sociology type stuff... it is like crack to them. I find blink especially powerful... it has lots of tests in it (and we know girls love tests). I've found talking about the book (even when they haven't read it)... really spawns great discussion.
