Keep up with it. Finish the Mistborn trilogy. Vin and Eland’s the romance are only a part of it. I like Vin, but I get those that don’t. The next Mistborn series, four books set hundreds of years in the future, has an older male lead and plenty of male and female characters like the first trilogy had. But the real masterpiece is the Stormlight Archives series, which is his largest scope story and has no central character. Plenty of men and women of various ages and stations. I think the Mistborn trilogy is worth reading first, and then Stormlight Archive which is a bigger and more epic investment if someone likes the Mistborn trilogy. It’s all part of the same broader universe, like how the Marvel movies all had the Thanos backdrop but with more depth than that.
