. . .in Crash, we get ideas thrown out but not developed, we have technology not explained, and we have a macroeconomy introduced but no indication as to how it actually works in lives at different points in the social hierarchy. This could have been a great pair of books but Crash ends up a crash.
The Ghoul King is a quick read, a few hours of adventure and intrigue in a strange new world. Then as it settles in and gets mulled over, it opens up and implies more story beyond what was read—quite a feat and very satisfying.
