Dylan Campbell, a CSIS officer, has been undercover hundreds of times before and is ready to get out of the game. But before he can tell his bosses at the Canadian spy agency, he discovers a terrorist plot that could take him---and millions of others---out permanently. Getting the information up the chain of command proves complicated, though, when Dylan's cover is blown and he's captured and thrown in an African prison. Will he be the first test subject for the new and deadly virus about to be unleashed on the world?American CIA officer Elizabeth Spencer is undercover for one reason---to find the virus being weaponized at a private hospital in Africa. When she meets Dylan, a Canadian photojournalist, she uses him to strengthen her story that she's only there to help. But the more she works with Dylan, the more the lines between professional and personal get blurred. She knows better than to get involved with someone while on assignment and the reason for that rule hits home when the terrorists' move up their timetable and Dylan is put in grave danger. Can she stand by and watch him die?With everything on the line, Dylan and Elizabeth have one chance to stop the terrorist attack before it reaches North America---but they have to make it to Greece. Can they break Dylan out of prison and stay alive long enough to prevent the release of the virus? Or will one or the other be called upon to offer the ultimate sacrifice?
