The novel “Ubik” by Philip K. Dick was published for the first time in 1969.

Glen Runciter is the owner of an agency that offers the services of inertials, people who can neutralize psi powers and thus prevent them from gaining access to business secrets. His wife Ella helps him even though she’s been dead for a long time because she’s kept in half-life in a so-called moratorium. Unfortunately, her conscience was attacked by the one from a boy in half-life whose mental signals are very strong.

Joe Chip, a technician employed by Glen Runciter, meets Pat Conley, who has the power to change the past. The agency receives an request for inertials from a company based on the Moon and Runciter decides to include Pat as well in the intervention team. The job on the Moon turns out to be a trap but it’s only the beginning of a series of strange events.
