Ubik by Philip K. Dick, 1969. Working on a series of PKD titles as a personal project: Glen Runciter runs a lucrative business—deploying his teams of anti-psychics to corporate clients who want privacy and security from psychic spies. But when he and his top team are ambushed by a rival, he is gravely injured and placed in “half-life,” a dreamlike state of suspended animation. As consumables deteriorate and technology gets ever more primitive, the group needs to find out what is causing time shifts and what a mysterious product called UBIK has to do with it all.
