Quirky, open to multiple interpretations, but then that's classic P.K.Dick. This novel was more muddled than I expected. The rare animals goes a long way to explaining this post apocalyptic world, but the empathy boxes and Mercerism feel like they were tacked on later. In comparison to the film, this book explains the empathy test (and others) better. By the end, we have unsettled questions on what it means to be human. Overall - cautious recommendation? I may have enjoyed the book more if I wasn't such a fan of the film.
