"Kola Peninsula, 1987. High in the Soviet Arctic, a tiny village houses an apocalyptic secret ... When research zoologist Dr Amelia Blackburn ventures north to investigate the ravages of the Chernobyl reactor meltdown, she stumbles on the evidence of another sinister disaster on the Norway-Russia border - one that appears far from innocent. Mother Russia will stop at nothing to prevent this information from being revealed, putting Amelia and her team in grave danger from the moment they leave the site. Major Tom Fox thought he'd put his intelligence career behind him, but wrapped in a custody battle for his young son, Charlie, a request from his high-ranking father-in-law forces his hand. When the reluctant spy reaches Russia, it quickly becomes clear that this is no ordinary mission."
