Dr. Grace Augustine must fight the clock—and politics—to stop an unprecedented disaster in this untold story set over a decade before the events of James Cameron's award-winning Avatar!

Years into the advent of the Avatar program on Pandora, pressure to bridge the divide between human and Na’vi has hit a peak. Dr. Grace Augustine realizes the best way to ease tensions is to learn from one another—sharing knowledge and gaining a mutual understanding of each other’s ways of living. She begins negotiations to open a school for Na’vi children, but her plans to repair relations leads to unintended consequences.

After a visit to Hell’s Gate, the Na’vi children succumb to a virulent illness and as the affliction escalates, so do accusations of betrayal and malice. Grace must navigate human politics to work with the Na’vi to find a cure . . . but can they trust her?
