In the jungles of Paraguay, Dr Aimee Weir and her team are in trouble. While drilling deep into the Earth a contagion strikes, their camp is quarantined, but workers start to vanish in the night. Is it fear of contamination - or has something far more lethal surfaced? Alex Hunter - code name Arcadian - and his Hotzone All-Forces Warfare Commandos are dropped in to the disaster area to do whatever it takes to stem the outbreak. But for the mission to be a success, the Arcadian must learn to master his violent inner demons long enough to confront the danger that not only threatens his own immediate survival, but that of mankind.
