Modeen: Insurrection. Jo Modeen, #11

NatSec agents are going missing. When an attempted systems breach is detected, and two operatives on a covert mission fail to report in, the Western Australian team leader alerts national operations manager Jack Pender, who dispatches interstate agents to provide on-ground assistance. But when those agents and the WA team leader are found dead in Perth HQ, Jack calls in the big guns, NatSec's top-ranking Queensland team.
Jo Modeen's team. Who are about to face their deadliest foe.... Modeen: Insurrection is the eleventh book in the high-action Jo Modeen series. The stories in this series can stand alone but are best enjoyed when read in sequence.
