Emmi Itäranta’s 2015 standalone secondary world fantasy Kudottujen kujien kaupunki was published in 2016 as The City of Woven Streets. And also as The Weaver (for some reason I cannot comprehend).

Those deemed Tainted are isolated, a precaution to prevent the spread of Taint. This has not been working well. The island’s rulers do the only sensible thing: double down on enforcement. It’s a small, harsh world.
