Book #4 of the Rogue Team International series.
"A covert group is infiltrating the world’s most secure bio-weapons research sites. All across the country, people are acting as human ‘disease bombs’ by infecting themselves and walking into public places. And heavily-armed groups of illegal private soldiers are massing for some unknown strike. Joe Ledger and the members of Rogue Team International, still reeling from the devastation and heartbreaking losses of their last mission, are forced into relentless action to try and save the country, if not the entire world."
