The "First Break All The Rules" title sounds familiar - I may have read that awhile ago, while working for another company.
A book I recommend (though the title seems off-putting to some) is
"Leadership Secrets of Attila the Hun". The book puts the needs of people in leadership and subordinate roles in an unusual perspective that I think resonates with the types of people we often have working with us.
I'm glad you're taking the time to do these reviews. I've tried it in fits and starts, but it never seems to stick. I run out of time to prepare, they often seem disinterested, maybe other reasons too. But it never seems to get traction.
You must be approaching it differently than I am, as it sounds like conversation flows pretty freely.
