The book rewarded rereading. In fact, it managed to become an entirely new story upon every subsequent reread, each time from a new point of view. Or, sometimes, from a point of view so thoroughly redefined as to become a new character, for all intents and purposes
Most stopped at their fifth or sixth reread, not because of a sense of having understood it all, but because things ended in a nice place this way. Some, however, had pushed the boundaries and were now at their nineteenth successful redefinition of the narrative, each reread as dramatic as the last one. When asked, however, their responses were either vague or incomprehensible; it is unclear whether this stems from a fear of spoilers, or the impossibility of communicating their understanding to those not already in the know

The response from the fanbase was immediate and surprisingly coherent:
The dog? The dog! The dog! The dog? The dog!
