I've been doing some research on the topic of storytelling and David Boje's Narrative methods looks to me as a very useful resource. David is a very active writer and also has his own website Storytelling Organization. Take a look at them.
The book is very intelectually demanding, explaining quite easily the most difficult french postmodern thought: Derrida, Ricoeur, etc. If you like this kind of stuff you will love it.
