Haunted by a mistake that cost lives during his second tour of duty in Afghanistan, Maric buries his demons in the farming communities of New Zealand - until his old SAS boss pulls him back to a world he has struggled to forget. Some of his SAS comrades, now retired, have died in suspicious circumstances. Maric follows the trail to the Finn, a gun for hire who models himself on Carlos the Jackal. Determined to avenge their deaths, he joins an undercover operation deep into headhunter territory in Kalimantan (Borneo). He and his team are expected to test experimental weapons decades ahead of their time, and destroy the diamond smuggling operation that is funding an East European crime syndicate. He soon discovers the Finn is heading a security force of Spetsnaz and mercs, and his plans start to unravel. Will Maric be able to signal the main force for a HA/LO drop over the Kalimantan jungle in time? Can he assimilate into his team the intel officers forced on him by the mission's financial backers? How will he get his teammates back when some of them are captured? Will he be able to best the Finn?
