Player Piano by Kurt Vonnegut
This is Vonnegut's first novel. Hard for me to believe that - it has so much happening here and so much to say about how people derive meaning and sense of identity. In some ways, the science fiction elements haven't aged well (he couldn't predict self-driving cars despite all the other tasks automated?), and there are some troubling gender politics. But I recommend it for both dystopia fans and Vonnegut fans. As always, there are some turns of phrase that capture an entire philosophy in 9 words.
