What is your approach to series?

Heh 'only'.
I can't think of any other series that are 15 books (although I'm sure there could be at least some, I'd be prepared to say it's not common)

Wheel of time is currently 11 books (book 12 will be published in october, I think), and probably will be 14 or 15 when it's done.

Fables is currently 13 volumes and going, but I don't know if you can compare graphic novels with written books.
