Probably I just want Scott's work to be Point of Dreams again, or something with the same layered depth and throw-away world-building. (Even Armor of Light has multi-layers, even if I don't much care for them.) And instead it's straight linear narrative, WYSIWYG: popcorn instead of a full course meal.
I do wonder sometimes if what really caught me in Point of Dreams was the cover of the original publication. It certainly sets you up for the kind of strangeness the real 17th century was prone to, that gets echoed in Astreiant with its functional astrology and phytomancy and its city government that certainly isn't ours. But cover or no, PoD is a grabber; imaginary or no, Astreiant is full of sense of place; and I miss that from Scott's later works.
