I read a lot of science fiction and fantasy, genres filled with long running book series. Until the last couple of years, I mostly avoided any series that wasn’t already complete. First, I don’t like truly “epic” sci-fi fantasy. On-going series without an end in sight, or series that go beyond roughly 3,000 to 4,000 pages never end well for me1. I simply lose interest. Second, I worry that series won’t actually reach completion, either because the books are not successful enough or the author gets writer’s block2, or even just getting caught up in waiting way too long between books3.
