The Windscale Incident is set in 1950s Britain, in an alternate timeline resulting from the Windscale Incident, a real event which took place on 10 October 1957. The UK's worst nuclear accident, the incident involved a fire breaking out at the Windscale nuclear facility and spreading nuclear radiation over the vicinity, resulting in an estimate 250+ cases of cancer. The UK's nuclear decommissioning plant Sellafield was later built on the same site.
Kearney's novel sounds like it will be using the incident as a divergence point for a new timeline. The blurb is as follows:
A blistering 1950’s Alternate-History Apocalypse that marks the beginning of a major new trans-media franchise.
Great Britain, mid-1950s.
Everyone remembers where they were when they heard the news. The simultaneous meltdown at the Windscale Nuclear Reactor and the Calder Hall site in the North of England killed thousands, but what came next was worst. The radioactive cloud, dispersed by heavy winds, effectively cut Great Britain in half and created the Exclusion Zone.
Hysterical accounts of strange creatures, wolf-like packs and bands of human survivors abound, but no really knows since the last expedition was lost fifteen months ago.
But there are mysteries that must be illuminated, and for Doctors Brian Mortlake and Constance Garraway, aided by a crack team of British soldiers, it’s time to enter the Zone.
More news on the book and the "trans-media franchise" as we get it.
