I read Philip K Dick's We Can Build You yesterday. I think it's my favorite of his novels I've read yet (aside from VALIS). I love how it purports to be about the whole concept of creating perfectly life-like simulacras of historical humans, and the societal ramifications thereof, but ends up being a meditation on mental illness and obsessive love, with the whole android thing being basically a subplot. You can really feel how his focus turned somewhere in the middle as he was writing it. Normally this would indicate a poorly written novel, but with Dick it just once again highlights his grander ambitions outweighing his identity as a 'pulp' sci-fi writer.
