If you enjoyed the shape of stories you might want to check out "Tempo: timing, tactics and strategy in narrative-driven decision-making". A good chunk of it is on graphing narratives.

Great book. Last time I checked that guy (Venk Rao) had gone off the political deep end on his blog, but the early stuff is very good.

The Gervais Principle is another saga of his worth reading in its entirety (much better than just finding a summary of it somewhere).

I stopped reading his blog as it got longer and longer and I got less and less signal out of it. Haven't checked in years.
