This article talking about charisma and a pastor's son reminds me of a book. A few months ago I stumbled upon "Handbook of Leadership Theory for Church Leaders - Drury Writing": http://www.drurywriting.com/sharon/Handbook-LeadershipTheory...

What I loved was how it related academic leadership theory to a field seldom covered but in which leadership is very important. Also it is very easy to read for non academic people.
