Valis by philip k dick.
Funny, sophisticated gonzo writing years before hunter s.thompson appeared on the scene. Also generally insane. Philip K dick loved to take care and be abused by really sick women just because he didn't want to be alone. He takes in a fiance with cancer who constantly boasts about screwing other men and stuff, also a lot of great history--especially james pike. That motherf-er was crazy
