The only hope for humanity isn't human. But she's fighting to stop a war that could destroy them all. Books 1-3 in the Partials series. PARTIALS:In a world where people have been all but wiped out by a virus created by part-human cyborgs called 'Partials', and where no baby survives longer than three days, a teenage girl makes it her mission to find a cure, and save her best friend's unborn child. But finding a cure means capturing a Partial. FRAGMENTS:Venturing deep into the wasteland, Kira's only allies are an unhinged drifter and two Partials who betrayed her yet saved her life - the only ones who know her secret.
Back on Long Island, what's left of humanity is gearing up for war. But their greatest enemy may be one they didn't even know existed. It is the eleventh hour of humanity's time on earth; this journey may be their last. RUINS:Humans and Partials alike are on the brink of destruction, and their only hope is to work together. But there is no avoiding it - the final war to decide the fate of both species is at hand, and every faction seems determined to tear the others apart. Both sides hold in their possession a weapon that could destroy the other.
Kira has fought her way through madness and ruin, but the greatest horror lies in a place she had never dared to consider: herself. She has one chance to save both species and the world. But it might be at the cost of her life.
