When Squadron Leader Adam Haylock, RAF, receives an unexpected posting and secondment to the UN Antarctic Interceptor Force at Teniente, Rodolfo Marsh Martin airbase on King George Island—latitude 62° south, over five hundred miles south of Tierra Del Fuego, he is totally unprepared for all the events that will subsequently unfold and change his life forever.

Arriving at his new base, he is also surprised to find himself reunited with an old adversary, Wing Commander Mike Prendergast as well as a former chum and comrade in arms, Flight Lieutenant Sam (Dobbo) Dobson whom he hasn’t seen in several years.

Once Adam learns the truth about his posting and begins to realise that something extremely sinister is happening south of the sixtieth parallel, events rapidly overtake him as he comes into serious conflict with Prendergast and the Wing Commander’s secret and sordid past begins to manifest itself and ultimately becomes apparent.

However this also has the effect of beginning a close collaboration between Adam and Dobbo that ends partly in tragedy for someone but which ultimately results in some incredible shared experiences as well as numerous utterly mind-blowing revelations of the stunning truth regarding what lies beyond Sixty Degrees South.
