Brain Dead - Augmented book 4

Disaster has struck. Rebels have rendered Neraka defenceless, leaving thousands of innocents at the mercy of the largest zombie horde ever recorded. Total annihilation seems inevitable. Yet still, amidst the chaos of war, John and his dwindling crew refuse to surrender. They have the brains and guts to win the fight against the undead, and they're making new alliances. Plus, finally, the facts of the zomb-augpocalypse are within reach. Newer, deadlier threats are on the horizon, however. Technology is being used against the AugFrees. For once, zomb-augs are not at the top of the food chain. Facing murderous cyborgs and crippling nanotech, John must be at his cleverest to survive. If he fails, the family he's building is doomed. But will his new-found responsibilities, along with the rise of the most dangerous traitor thus far, prove too much? Can John beat the odds again, or will he and his fellow Nerakans wind up as dead as the monsters at the gate?
