A wild ride from one of the twentieth century's most brilliant -- and neglected -- science fiction and horror writers, whom Stephen King called “the best writer of science fiction that England has ever produced.”

Johnny Farthing is your average photojournalist until his fiancée goes missing and women who look suspiciously, uncannily similar to her start turning up dead. As Johnny descends a rabbit hole of doppelgängers, mysterious American senators, and eerie bureaucracies, it becomes clear that these peculiar similarities are part of far bigger and deadlier plans -- and that the fate of the world just might be at stake.
