Former intelligence officer Kade Sims returns in SOURCE, assigned a new identity and double duty. He’s working for the Recovery Team, a secret task force charged with eradicating the high-tech insurgency known as The Chapter. The FBI also contracts him to collect information on his attractive former colleague, Lin Soon, now suspected of working with Chinese intelligence. When an India-China territorial dispute creates a crisis, the US becomes the target of a mysterious bioweapon, and evidence of The Chapter's offshore operations surfaces. As Kade digs into Lin’s involvement and tries to determine her loyalties, he must also push the limits of the technology inside him to confront The Chapter’s deadly network—if he’s not hunted down first.
