Absolutely brilliant! This is the rare book which marries really in-depth, interesting philosophy with a strong focus on characters who feel deeply and fundamentally human. This is the kind of nuance which has, unfortunately, been flattened by both film adaptations, so it really is worth returning to the source - This is such a different beast from either Blade Runner. Dick balances two contrasting point of view characters impressively deftly and through it all is this beautiful, horrible depiction of a world dissolving into rubbish ("kipple", in the book's vernacular), its sad current inhabitants and what feel like its inevitable inheritors, with no one really coming off well - Empathy is lionised throughout but the reader gets the sense that it has been lost somewhere along the way. It is the most compelling post-apocalypse I have ever read. Read it! Following that, maybe read it again - It is short enough to re-read and I have the sense that it would certainly reward it!
