Jack Bedford may be the rightful King of Britain, but he’s going to have to work for it. In the years since the Cull wiped out most of the human race, the beleaguered island has survived invasions, murderous cults and civil wars.

A fresh disaster may give him the chance to prove his leadership. Heysham power plant, in Lancashire, has suffered a catastrophic meltdown, the aging safety mechanisms failing after years of neglect. Hundred have been killed or fatally poisoned.
