Jane turns her phone on after a flight to learn that her husband Jim, hale and healthy a few hours ago, has died. When she arrives at the hospital where they both work, she finds his body is there only from the neck down: his head has been removed by a strange organisation, Polaris, and placed in cryogenic storage at Jim’s request. From there, the narrative bifurcates, alternating chapters between Jane’s grief and fight against Polaris, and Jim’s reawakening sometime in the distant future.
