A multi-layered novel which uses quantum physics as its basis with the 'now' story interspersed with
a chronicle from the mid 19th century and another from the early 1920s, both referring to real life people though the history of the latter seems distorted. The current activity is set in a parallel world where Scotland is a separate country under totalitarian rule. The main character is a physicist who has been invited to aresearch facility in the Highlands to continue his work while helping to build a
new device. He is convinced this could spell the literal end of the world by multiplying the number
of possible worlds that might appear, all this based on quantum theory. Despite the esoteric nature of the plot's basis, the work moved along briskly and held my interest.
