Series vs. Recurring Characters
In the comments thread for Will the Series be Unbroken, Brad & Imani‘s insights made me realize that I was thinking of series in a very limited way. I was only considering a series as having the following criteria: Set in the same world Recurring characters A forward-moving story that aims for cohesiveness across multiple books There is a discrete end in sight, whether or not the author ever reaches it (coughrobertjordan) In other words, the common model in the fantasy/sci fi world.
