This was definitely one of Philip K. Dick’s stranger novels, as you’re not quite sure what’s going on until the very end, and even then you have to wonder a bit, too. In a world in which telepathy and precognition are common, salable talents, Glen Runciter’s agency is hired to block some spying on a secret project on the colony on the Moon. From there on, things get a bit weird…and then Ubik shows up.
Well-written and amazingly detailed, this is good, proper science fiction the way it’s supposed to be handled. It’s also an excellent treatise on consumerism. Definitely recommended.
