I'll admit that after a year or two, and reading newer Heresy novels, I wouldn't score it that high anymore. I would actually say now that Fear to Tread
is about an 8.4/10, which to me is a Very Good book. I still think it's in the Top 10 Heresy books, but not the Top 5 anymore, due to new releases displacing it.
I may do a re-read soon and re-evaluate my thoughts.
