Piers Anthony's 7 book series which begins with the book "Split Infinity"
Robert Jordan's 11 book series (The Wheel of Time) which begins with "The Eye of The World". Many have a real love/hate relationship with these books but I love them for the reason most people hate them. I enjoyed Jordan's worldbuilding and writing style. The folks who really love this series are engaged by the rich world unfolding and in no hurry to get to the "conclusion" of the story (stories). And I well understand those who hate the series
I just like to read and enjoy the journey, I don't really like to finish books that I enjoy reading so this suits me well. As with several "epics", if reading this - I suggest skipping prefaces and forewords and going straight for Chapter 1. But your mileage may vary.
