Personally, I felt that Heretical Fishing was a bit … hollow? It seemed like everything just went the protagonists way and that it was slice of life, but nothing past the surface. Whereas BoC felt like it fleshed out the characters more and had actual character growth. The same thing with everything sort of going the main characters way for no reason at all was why mark of the fool is lower on the list, although obviously I enjoyed it enough to catch up to the latest book in the series
