She survived the virus and the Acceptance trials. But can she survive the lies. Tylia Coder is the bridge between worlds. Born of the GEOs underground, she's one of only two known victors of the Acceptance trials - a survival contest that promises to prevent infection from the GM virus that nearly wiped out humanity decades ago. Now with precious antibodies in her blood, she may finally hold the key to finding a cure. Leaving her dark home in the GEOS behind as well as her blossoming relationship with Skylar Two, Tylia is determined to invoke change as she moves up to the Greens - an area in the Labs with floating sky cities, bright lights and lush forestry. But the life she envisioned living here is far from the reality she faces on arrival. Access to information is restricted. Questions she asks are left unanswered. Communication with her family in the GEOS is cut off. And someone's spreading lies about the Rejs, a group of outlaws living on the surface, who now claim her as one of their own. Worst of all, members of the Farrow family are tormenting those who threaten their way of life. And when Tylia is overheard defending the Rejs, the Farrow's set their vicious sights on her. To shield herself from yet another "accidental death" in the Labs, she has no choice but to accept a partnership proposal from the only Farrow willing to befriend her, the too-perfect Ben. But Tylia soon realizes she'll need to act fast if she's to save not only herself and her loved ones in the Rejs and the GEOs, but what also remains of the human race.
