The Kingkiller series. Before learning more about media theory and all that, I LOVED those books. To the point that I was depressed after finishing A Wise Man's Fear (book #2).
Going back to read them, they feel a bit immature and remind me of an early 20's version of myself and honestly when book three comes out I'll take a pass. I've aged out of the series and tbh the author is a really aggressive jerk and that really ruined my desire to support him in any way.
